Why is the T7 polymerase gene in E. coli strain BL21(DE3) under the .pdf
Why is the T7 polymerase gene in E. coli strain BL21(DE3) under the control of an inducible
promoter?
Solution
The T7 polymerase gene in E. coli strain BL21(DE3) under the control of an inducible promoter
because many expression plasmids often use these \"inducible expression system\" when adding
inducible promoters such as \"IPTG\" to the medium. These inducible promoters are going to
prevent formation of dead cells by promoting synthesis or protein expression of T7 RNA
polymerase in E coli cells finally growth phase of cells will be health to reach appropriate \"cell
density\". Therefore, these inducible promoters are going to activate expression of plasmid
systems using medium finally these inducible promoters control problems produced via toxic
protein products formation.

MTBF: Mean Time Between Failure
It is a dependability term used to give the amount of failures per million hours for a product. This
is the most common examination about a product’s life duration, and is significant in the
decision-making procedure of the end user. MTBF is significant for business and integrators than
for consumers.
MTTR : Mean Time To Repair
It is the time required to restore a failed hardware component. In an operational system, repair
generally means restoring a failed hardware element.
RPO: Recovery Point Objective
It expalin the period of time that pass during the disturbance before the amount of data lost
during that period exceeds the Business plan\'s maximum acceptable threshold.
RTO: Recovery Time Objective
It is the period of time and a service point within which a business process must be restored after
a disaster in order to avoid improper penalties connected with a break in continuity..

vapour pressure equation The Clansius-Clapeyron relation relates the.pdf
vapour pressure equation The Clansius-Clapeyron relation relates the slope of (for example) the
vapour pressure curve to latent heat L and the change in volume. Neglecting the volume of the
liquid phase relative to that in the vapour phase, and assuming the latent heat to be independent
of temperature and pressure (this is often valid for sufficiently short segments of the curve),
show the vapour pressure equation P = const times e^-l/(RT), where l = L/n is the latent heat per
mole.
Solution
The equilibrium between water and water vapor depends upon the temperature of the system. If
the temperature increases the saturation pressure of the water vapor increases. The rate of
increase in vapor pressure per unit increase in temperature is given by the Clausius-Clapeyron
equation. Let p be the saturation vapor pressure and T the temperature. The Clausius-Clapeyron
equation for the equilibrium between liquid and vapor is then
dp/dT = L/(T(Vv-Vl))
where L is the latent heat of evaporation, and Vv and Vl are the specific volumes at temperature
T of the vapor and liquid phases, respectively.
More generally the Clausius-Clapeyron equation pertains to the relationship between the
pressure and temperature for conditions of equilibrium between two phases. The two phases
could be vapor and solid for sublimation or solid and liquid for melting.
The material below is an examination of the application of the Clausius-Clapeyron equation to
meteorology where the most relevant systems are water and water vapor and salt water and water
vapor. But the equation also applies to ice and water vapor and ice and water. Finally there is a
derivation of the Clausius-Clapeyron equation from thermodynamic principles.
Note that Vv is much greater than Vl so that to a good approximation
dp/dT = L/(TVv)
Furthermore the ideal gas equation applies to the vapor; i.e.,
pVv = RT
and hence
Vv = RT/p
where R is the universal gas constant.
Thus
dp/dT = L/(RT²/p)
or, equivalently
(1/p)(dp/dT) = L/(RT²)
In differential form this is
dp/p = (L/R)(dT/T²)
or, equivalently
d(ln(p)) = (L/R)d(-1/T)
If L is independent of temperature then the solution to the differential equation is
ln(p) = c0 - (L/RT)
or, equivalently
p = c1exp(-L/RT)
where c1 is a constant..

The Vietnam War Era
Discuss the range of American responses to the war.
How did they change over time?
How did domestic political concerns shape the country\'s response to the war?
How did the war shape domestic politics in the 1960s and early 1970s?
Reference:
Goldfield, D. R., & In Wheeler, R. A. (2014). The American journey: A history of
the United States, Combined Volume (7th ed.). Upper Saddle River, N.J.:
Pearson
Solution
In the United States, a nationwide debate ensued over participation in the war. The government\'s
official position was that it was involved in Vietnam at the request of the government of South
Vietnam and was helping to repel Communist aggression from the north. Its only avowed
objective was to secure a settlement that would allow the people of Vietnam to decide their own
form of government. To achieve this end, it was using only carefully controlled military
measures so as not to take innocent lives or bring about active participation by China or the
Soviet Union.
As United States involvement continued, however, Americans grew increasingly dissatisfied
with their nation\'s war policy. Some, described as \"hawks,\" argued that the United States
should use maximum military force to gain a quick victory. Others, called \"doves,\" argued that
the conflict in Vietnam was essentially a civil war in which the United States had no right to
interfere. Some of the doves demanded immediate American withdrawal, while others called for
a gradual disengagement from the war.
Some critics of the war charged that American use of bombers and of artillery was too
indiscriminate and that many innocent civilians had perished. The revelation that United States
troops in 1968 had massacred the entire population of My Lai, an enemy-held village, caused
much controversy over the way in which the war was being fought. Demonstrations were held in
the United States, especially in 1969 and 1970, to protest the war.
As the Vietnam War progressed, it lost much support from Americans because it was clear to
many that it was not justified. This caused for the country to view war as destructive, and
brought about a peace movement that is mostly associated with the decade of the 1960\'s but
lasted until the late 1980\'s..

I am stuck on parts E and F
Exercise 1: NumberListTester.java
Class NumberList implements a simple list of Integers, using an ArrayList. NumberListTester
generates 10 random, positive, 2-digit ints, and adds them to the list. It then calls method
printList which prints the items on the list.
Run the program until you understand what it does.
a. Write the body of the method printReversed, which prints the list items in reverse order. Add a
statement in main to call printReversed after the call to printList.
Check ______
b. Write the body of the method printEveryOther, which prints every other item on the list,
beginning with the first one. In main, replace the statement that calls printReversed with one
that calls printEveryOther.
Check ______
c. Write the body of the method printEvens, which prints all the even-numbered ints on the list.
In main, replace the statement that calls printEveryOther with one that calls printEvens.
Check ______
All this printing is getting a bit tedious. Let\'s try some more fun operations.
d. 0. Add a new ArrayList-of-integer instance variable called bigList to the NumberList class
Add a statement to the NumberList constructor that creates an empty ArrayList object pointed to
by bigList
Delete the call to printEvens from main.
Write the body of the method splitList, which copies all ints that are greater than or equal to 50
from aList to bigList.
Add a method to the NumberList class to print bigList.
Add a sequence of method calls in main to verify that the splitList method is working correctly.
I.e., after calling splitList, call again the method that prints the original list and then call the
method you wrote in step 4 to print the bigList.
Check _____
E. Add a method insert to the NumberList class that takes two parameters of type int. The first
parameter is the index at which to insert a new number into the list, and the second is the number
to be inserted. E.g., if the first param is 4 and the second is 37, then 37 will be inserted at index
4 in aList (i.e., as the new 5th list element). The number inserted does not replace the number
currently at that position, but is inserted just before it.
Hint: The ArrayList class has a method that does exactly this. Call that method from your insert
method.
Now add statements to main to allow the user to specify the number to insert and the position at
which to insert it. Then, after inserting the new number, print the updated list.
Check _____
F. Finally, add code to your insert method that will assure that an IndexOutOfBoundsException
cannot be thrown. I.e., your insert method should just print an appropriate error message if the
first parameter --- the index at which to insert the new Integer --- is illegal.
Hint: What are the legal indices for an ArrayList? What is the smallest? What is the largest?
What about the special case of inserting a new value at the end of the list? Try it!
Check _____

How does differ from evolution systematic Only cladistics traces e.pdf
How does differ from evolution systematic? Only cladistics traces evolution relationship and
construct classifies that reflects these relationship. Only evolution systematic recognizes that
organisms must be compared using specific characters. Only cladistics rigorously defines the
kinds of homologies that yields the most useful information. Only clasdictics uses homologous
traits to trace to apply evolution relationship Why is the paleospcc.es concept more difficult to
apply to organisms than the biological and the ecological species concepts? Because
reproductive isolation cannot be studied directly Because ecological distinction are difficult to
impossible be past environments Because neither exclusive mating nor ecological separators are
usually accessible us fossil specimens. Because homologous Waits are rarely expressed In fossil

species. When general and specialized traits of organisms are considered in evolution it is
important to recognize that only a generalized ancestor can profit from the flexible evolutionary
basis for rapid diversification Which of the following animals is an appropriate example for a
highly specialized placental mammal that is structurally to a narrow, rodent/woodpecker-like
econiche: The duck-billed platypus. The wallaby. The white-tailed deer. The aye-aye of
Madagascar.
Solution
41. B. Partial reproductive isolation of two populations.
Parapatric speciation
occurs when populations are separated not by a geographical barrier, such as a body of water, but
by an extreme change in habitat. While populations in these areas may interbreed, they often
develop distinct characteristics and lifestyles. Reproductive isolation in these cases is not
geographic but rather temporal or behavioral.
42. B. 3.5 billion years.
The oldest known fossils, are cyanobacteria from Archaean rocks of western Australia, dated 3.5
billion years old.
43. B. How bones mineralize during fossilization.
Taphonomy is the branch of palaeontology that deals with the processes of fossilization.
44. C. The aye aye of Madagascar.
From an ecological point of view the aye-aye fills the niche of a woodpecker, as it is capable of
penetrating wood to extract the invertebrates within..

Solution
Considering nitrogen, phosphate, and potash (NPK). All these when used in lawn would promote
growth of the plants but an excess use may cause problems.Excessive amount of nitrogen and
phosphorus run off from the soil into the water bodies causing eutrophication which results into
excessive growth of algae and results into algal bloom. This can deplete bottom dwelling
organisms from nutrients and sunlight. Thus, causing water pollution..

Do the data shown in the boxplot below have a greater amount of vari.pdf
Do the data shown in the boxplot below have a greater amount of variability within levels A, B,
C, and D or between the four levels? Explain.
Solution
By inspection, we see that the 4 intervals pretty much coincide. Thus, there is small variability
between levels.
Also, we see that the intervals are quite long. Thus, there is great variability within the level.
Thus, there is greater variability WITHIN LEVELS than between levels. [ANSWER].
Architectural Innovation The Reconfiguration of Existing Product Te.pdf
Architectural Innovation: The Reconfiguration of Existing Product Technologies and the Failure
of Established Firms\" defines four types of innovations: incremental, modular, architectural, and
radical. Established and stable firms are inherently organized such that incremental and modular
innovations are successfully handled. Radical innovations are easily recognized and are managed
accordingly by forming specialty design groups to develop them. Architectural innovations use
existing core design concepts in a new architecture that have a significant impact on the
relationships between components than on the technologies of the components themselves.
Architectural innovations are often mistaken for incremental innovations. Management needs to
be able to identify architectural innovations such that proper resources are allotted and design
groups are restructured.
Questions
How are component versus architectural knowledge managed inside an organization?
How do you identify an architectural innovation?
How do you allocate existing resources to develop an architectural innovation successfully?
Solution
(1) Answer:- Component knowledge is very useful for organization . Component knowledge is
the knowledge that relates to a subroutine or discrete aspect of an organization’s operations. It is
knowledge that relates to parts or components rather than the whole.
Architectural knowledge, conversely, relates to the whole that is, to organization-wide routines
and schemas for coordinating the various components of the organization and putting them to
productive use.
(2) Answer:- We can identify architectural innovation in organization by help of this.
Architectural innovation is useful and needs to be applied in the new product, but some of what it
knows is not only not useful but may actually handicap the firm.
(3) Answer:- Architectural innovation presents established firms with a more subtle challenge.
Architectural innovation is embedded in channels, filters, and strategies, the discovery process
and the process of creating new information usually takes time..
Discuss the major capabilities of DBMS and why is a relational DBMS .pdf
Discuss the major capabilities of DBMS and why is a relational DBMS so powerful?
Solution
DBMS :-
DBMS is a software or tool which can be used for managing and maintaining the data within the
database.
Major Capabilities of DBMS :-
1.Data Storage
2.Data Retrieval
3.Data Update
4.Security
5.Data Independence
Explanation :-
Generally a person has to work with huge amount of information everyday. Inorder to interact
with the large amount of data we need a system where we can store, manipulate, security,
sharing the information all over the world. It is a core reason the industries are maintaining
database management tools.
A relational DBMS is so powerful. Because :-
* In RDBMS model the data will be stored in the form of tabular format. where as table is
nothing but a collection of rows and columns.
* RDBMS model will provide high level security by using authentication and autherisation.
* RDBMS maintains accurate and consistency of the data with the help of data integrity
mechanism.
* RDBMS supports the data manipulations by using DML commands.
* RDBMS provides faster rate retrieving the data by using index mechanism..

The Vietnam War Era
Discuss the range of American responses to the war.
How did they change over time?
How did domestic political concerns shape the country\'s response to the war?
How did the war shape domestic politics in the 1960s and early 1970s?
Reference:
Goldfield, D. R., & In Wheeler, R. A. (2014). The American journey: A history of
the United States, Combined Volume (7th ed.). Upper Saddle River, N.J.:
Pearson
Solution
In the United States, a nationwide debate ensued over participation in the war. The government\'s
official position was that it was involved in Vietnam at the request of the government of South
Vietnam and was helping to repel Communist aggression from the north. Its only avowed
objective was to secure a settlement that would allow the people of Vietnam to decide their own
form of government. To achieve this end, it was using only carefully controlled military
measures so as not to take innocent lives or bring about active participation by China or the
Soviet Union.
As United States involvement continued, however, Americans grew increasingly dissatisfied
with their nation\'s war policy. Some, described as \"hawks,\" argued that the United States
should use maximum military force to gain a quick victory. Others, called \"doves,\" argued that
the conflict in Vietnam was essentially a civil war in which the United States had no right to
interfere. Some of the doves demanded immediate American withdrawal, while others called for
a gradual disengagement from the war.
Some critics of the war charged that American use of bombers and of artillery was too
indiscriminate and that many innocent civilians had perished. The revelation that United States
troops in 1968 had massacred the entire population of My Lai, an enemy-held village, caused
much controversy over the way in which the war was being fought. Demonstrations were held in
the United States, especially in 1969 and 1970, to protest the war.
As the Vietnam War progressed, it lost much support from Americans because it was clear to
many that it was not justified. This caused for the country to view war as destructive, and
brought about a peace movement that is mostly associated with the decade of the 1960\'s but
lasted until the late 1980\'s..

Rewrite the expression as an algebraic expression of x Rewrite the .pdf
Rewrite the expression as an algebraic expression of x: Rewrite the expression as an algebraic
expression of x: sin (tan^-1 x)
Solution
sin(tan-1x)
let tan-1x=t
Therefore tan t= x
Here opposite=x and adjacent=1
Therefore hypotenuse=sqrt(12+x2) = sqrt(1+x2)
sin t=opposite/hypotenuse= x/sqrt(1+x2) x(sqrt(1+x2))/(1+x2)
Hence,sin(tan-1x)= x(sqrt(1+x2))/(1+x2).

Run the program until you understand what it does.
a. Write the body of the method printReversed, which prints the list items in reverse order. Add a
statement in main to call printReversed after the call to printList.
Check ______
b. Write the body of the method printEveryOther, which prints every other item on the list,
beginning with the first one. In main, replace the statement that calls printReversed with one
that calls printEveryOther.
Check ______
c. Write the body of the method printEvens, which prints all the even-numbered ints on the list.
In main, replace the statement that calls printEveryOther with one that calls printEvens.
Check ______
All this printing is getting a bit tedious. Let\'s try some more fun operations.
d. 0. Add a new ArrayList-of-integer instance variable called bigList to the NumberList class
Add a statement to the NumberList constructor that creates an empty ArrayList object pointed to
by bigList
Delete the call to printEvens from main.
Write the body of the method splitList, which copies all ints that are greater than or equal to 50
from aList to bigList.
Add a method to the NumberList class to print bigList.
Add a sequence of method calls in main to verify that the splitList method is working correctly.
I.e., after calling splitList, call again the method that prints the original list and then call the
method you wrote in step 4 to print the bigList.
Check _____
E. Add a method insert to the NumberList class that takes two parameters of type int. The first
parameter is the index at which to insert a new number into the list, and the second is the number
to be inserted. E.g., if the first param is 4 and the second is 37, then 37 will be inserted at index
4 in aList (i.e., as the new 5th list element). The number inserted does not replace the number
currently at that position, but is inserted just before it.
Hint: The ArrayList class has a method that does exactly this. Call that method from your insert
method.
Now add statements to main to allow the user to specify the number to insert and the position at
which to insert it. Then, after inserting the new number, print the updated list.
Check _____
F. Finally, add code to your insert method that will assure that an IndexOutOfBoundsException
cannot be thrown. I.e., your insert method should just print an appropriate error message if the
first parameter --- the index at which to insert the new Integer --- is illegal.
Hint: What are the legal indices for an ArrayList? What is the smallest? What is the largest?
What about the special case of inserting a new value at the end of the list? Try it!
Check _____

How does differ from evolution systematic Only cladistics traces e.pdf
How does differ from evolution systematic? Only cladistics traces evolution relationship and
construct classifies that reflects these relationship. Only evolution systematic recognizes that
organisms must be compared using specific characters. Only cladistics rigorously defines the
kinds of homologies that yields the most useful information. Only clasdictics uses homologous
traits to trace to apply evolution relationship Why is the paleospcc.es concept more difficult to
apply to organisms than the biological and the ecological species concepts? Because
reproductive isolation cannot be studied directly Because ecological distinction are difficult to
impossible be past environments Because neither exclusive mating nor ecological separators are
usually accessible us fossil specimens. Because homologous Waits are rarely expressed In fossil
specimens Parapatric specification is characterized by? Complete reproductive isolation of two
populations Partial reproductive isolation of two populations. No reproductive isolation of two
populations. Complete ecologic niche separation of two species What is the age of the oldest
known fossil found on Earth 3.8 billion years. 3.5 billion years. 2 billion years. 520 million
years. Taphonomy is the study of: What happens to organic matter after death. How bones
mineralize during fossilization. The rules of classification. Ancestral traits In closely related
species. When general and specialized traits of organisms are considered in evolution it is
important to recognize that only a generalized ancestor can profit from the flexible evolutionary
basis for rapid diversification Which of the following animals is an appropriate example for a
highly specialized placental mammal that is structurally to a narrow, rodent/woodpecker-like
econiche: The duck-billed platypus. The wallaby. The white-tailed deer. The aye-aye of
Madagascar.
Solution
41. B. Partial reproductive isolation of two populations.
Parapatric speciation
occurs when populations are separated not by a geographical barrier, such as a body of water, but
by an extreme change in habitat. While populations in these areas may interbreed, they often
develop distinct characteristics and lifestyles. Reproductive isolation in these cases is not
geographic but rather temporal or behavioral.
42. B. 3.5 billion years.
The oldest known fossils, are cyanobacteria from Archaean rocks of western Australia, dated 3.5
billion years old.
43. B. How bones mineralize during fossilization.
Taphonomy is the branch of palaeontology that deals with the processes of fossilization.
44. C. The aye aye of Madagascar.
From an ecological point of view the aye-aye fills the niche of a woodpecker, as it is capable of
penetrating wood to extract the invertebrates within..
Giving your lawn more nutrients than it can absorb, can cause polluti.pdf
Giving your lawn more nutrients than it can absorb, can cause pollution of streams rivers, takes
and oceans as the nutrients are washed out of the True False
Solution
Considering nitrogen, phosphate, and potash (NPK). All these when used in lawn would promote
growth of the plants but an excess use may cause problems.Excessive amount of nitrogen and
phosphorus run off from the soil into the water bodies causing eutrophication which results into
excessive growth of algae and results into algal bloom. This can deplete bottom dwelling
organisms from nutrients and sunlight. Thus, causing water pollution..

Do the data shown in the boxplot below have a greater amount of vari.pdf
Do the data shown in the boxplot below have a greater amount of variability within levels A, B,
C, and D or between the four levels? Explain.
Solution
By inspection, we see that the 4 intervals pretty much coincide. Thus, there is small variability
between levels.
Also, we see that the intervals are quite long. Thus, there is great variability within the level.
Thus, there is greater variability WITHIN LEVELS than between levels. [ANSWER].
Architectural Innovation The Reconfiguration of Existing Product Te.pdf
Architectural Innovation: The Reconfiguration of Existing Product Technologies and the Failure
of Established Firms\" defines four types of innovations: incremental, modular, architectural, and
radical. Established and stable firms are inherently organized such that incremental and modular
innovations are successfully handled. Radical innovations are easily recognized and are managed
accordingly by forming specialty design groups to develop them. Architectural innovations use
existing core design concepts in a new architecture that have a significant impact on the
relationships between components than on the technologies of the components themselves.
Architectural innovations are often mistaken for incremental innovations. Management needs to
be able to identify architectural innovations such that proper resources are allotted and design
groups are restructured.
Questions
How are component versus architectural knowledge managed inside an organization?
How do you identify an architectural innovation?
How do you allocate existing resources to develop an architectural innovation successfully?
Solution
(1) Answer:- Component knowledge is very useful for organization . Component knowledge is
the knowledge that relates to a subroutine or discrete aspect of an organization’s operations. It is
knowledge that relates to parts or components rather than the whole.
Architectural knowledge, conversely, relates to the whole that is, to organization-wide routines
and schemas for coordinating the various components of the organization and putting them to
productive use.
(2) Answer:- We can identify architectural innovation in organization by help of this.
Architectural innovation is useful and needs to be applied in the new product, but some of what it
knows is not only not useful but may actually handicap the firm.
(3) Answer:- Architectural innovation presents established firms with a more subtle challenge.
Architectural innovation is embedded in channels, filters, and strategies, the discovery process
and the process of creating new information usually takes time..
Discuss the major capabilities of DBMS and why is a relational DBMS .pdf
Discuss the major capabilities of DBMS and why is a relational DBMS so powerful?
Solution
DBMS :-
DBMS is a software or tool which can be used for managing and maintaining the data within the
database.
Major Capabilities of DBMS :-
1.Data Storage
2.Data Retrieval
3.Data Update
4.Security
5.Data Independence
Explanation :-
Generally a person has to work with huge amount of information everyday. Inorder to interact
with the large amount of data we need a system where we can store, manipulate, security,
sharing the information all over the world. It is a core reason the industries are maintaining
database management tools.
A relational DBMS is so powerful. Because :-
* In RDBMS model the data will be stored in the form of tabular format. where as table is
nothing but a collection of rows and columns.
* RDBMS model will provide high level security by using authentication and autherisation.
* RDBMS maintains accurate and consistency of the data with the help of data integrity
mechanism.
* RDBMS supports the data manipulations by using DML commands.
* RDBMS provides faster rate retrieving the data by using index mechanism..

2.4. What are the differences between analogue and digital instrumen.pdf
2.4. What are the differences between analogue and digital instruments? What advantages do
digital instruments have over analogue ones?
Solution
Advantages of digital over analog instruments:
1) They are very easy to read.
2) Since there are very few moving parts in the electronic instruments, they are usually more
accurate than theanalogue instruments. Even the human error involved in reading these
instruments is very less, which adds to the accuracy of digital instruments.
3) The electronic items tend to be cheaper than the mechanical items.
4) The data from the instruments can be recorded for future reference.
5) The output of the digital devices can be obtained in the computerANALOG
INSTRUMENTSDIGITAL INSTRUMENTS1.Signals in continuous fashion,gives infinite no of

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Introduction to Quality Improvement Essentials
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

In hypothesis testing, what is a Type I error Type II errorSol.pdf
- 1. In hypothesis testing, what is a Type I error? Type II error? Solution In testing of hypothesis, {Type I error} is the error committed due torejecting the null hypothesis when it is true. {Type II error} is the error byaccepting a null hypothesis when it is false. REMARK: It is obvious that Type I error is more serious than Type II error.
