Quiz 51. The mean weight of the adults in a certain region is .docx

Quiz 5
1. The mean weight of the adults in a certain region is believed
to be . An agency thinks that this
mean may be higher than the above belief. They are going to
take a simple random sample of 100 adults for a hypothesis test
at 5% level of significance.
a) State the null and the alternate hypothesis for this test.
b) If the mean weight of the adults in the above simple random
sample is and we know that the population standard deviation
is , compute the test statistic and the P_value of the test.
c) Will you reject or not reject the null hypothesis at 5% level
of significance?
2. An expensive medication from a particular company states
100 ml for the contents on the bottles for this medication. An
agency would like to test if the bottles are being under filled, in
the sense that the mean contents of all bottles is less than 100
ml.
a) State the null hypothesis and the alternative hypothesis.
b) The contents in 10 randomly selected bottles were measured,
and the results are below in ml.
contents in ml

State the test statistic
State the P_value.
Does this sample show a good evidence at 5% level of
significance that the bottles are being under filled?
3. The electricity supply in a certain region appears to show a
lot of voltage fluctuation from the required value of 240 V.
To check if the mean voltage is different from 240 V, the
voltage will be measured at 15 randomly selected times.
a) State the null and the alternative hypothesis for this test.
b) The following are the readings shown by the 15
measurements.

a) Write the test statistic.
b) Will you reject or not reject the null hypothesis at 5% level

of significance?
c) Compute a 95% confidence interval for the overall mean
voltage based on the results from the above sample.
d) Does this interval contain the value 240 Volt?
e) Explain the usage of a 95% confidence interval for a two
sided hypothesis test for a population mean at a 5% level of
significance.
4.
In the past, 44% of those taking a public accounting qualifying
exam have passed the exam on their first try. Lately, the
availability of exam preparation books and tutoring sessions
may have improved the likelihood of an individual’s passing on
his or her first try. To test if the likelihood of passing in the
first try in now higher,
a simple random sample of recent applicants will be examined.
a) State the null hypothesis and the alternative hypothesis
b) In a sample of 250 recent applicants, 130 passed on their
first attempt. At 0.05 level of significance, can we conclude that
the proportion passing on the first try has increased? State the
P_value and a reason for your conclusion.

Two fair dice are rolled and the number of dots facing up is
added.
a) Find the probability that the sum of the dots facing up is 7.
b) Find the probability that the sum of the dots facing up is 11.
c) A game charges you a $1 to play and lets you roll a pair of
fair dice. It pays $3.00 (i.e. a profit of $2.00)
if the sum of the dots facing up is 7 or 11, otherwise

does not pay any money back.

implications of Mead and Cooley’s work, consider
the content of If Mirrors Could Speak, and the

look for examples of Mead and Cooley’s concepts in
the creepy social engineering film.

The
goal
of
this

at
least
a
bit
of
a
glimpse
into
the
world
of
professional
sociology
through
the
lens
of
peer-‐reviewed
scholarly
journals
(the
type
of
publications
you
find
on
sociologists’
coffee
tables).
Beyond
that,
the

goal
is
to
expose
you
to
current
research
in
general
and
specialized
sociology
journals.
Further,
this

up
your
skills
of
critical
thinking,
writing,
and
proper

citation.
Your
task
is
to
choose
an
article
of
interest
to
you
that
reports
on
empirical
sociological
research,
or
methods
of
conducting
such
research,
from
one

only
one

the
peer-‐reviewed

academic
journals
listed

book.
Instead,
you
may
only
choose
a

the
research
methods
we
have

covered
in
class.
Papers

criteria
laid
out
above
will
be
not
be
accepted
and
will
receive
a
grade
of
0.
Here
is
what
you

ought
to
do:
In
4

of
your
paper
II) Explain
what

the
general
purpose
is
of
the
research
you
are
reporting
on
(i.e.
What
are
the
research
questions?
Hypotheses?)
III) Tell
me
what
theories,
models,
or
concepts
are
discussed
in
the
article.
Provide

a
concise
explanation
of
the
key
theoretical/conceptual
issues
discussed
in
the
piece.
If
the
case
is
that
no
theoretical
or
conceptual
issues
are
discussed
in
the
article,
then
provide
a
discussion
of

what
theories,
models,
or
concepts
from
class
that
might
be
a
good
fit.
IV) Research
Methods
a) Sample/subjects
(Who?
How
Many?
How
were
the
data
obtained?
Where?)
b) Data
collection
method
and
procedures
(Does

the
article
report
on
an
experiment?
Series
of
interviews?
Etcetera.
Provide
me
with
some
details
of
the
data
collection
procedures
utilized)
c) Ethical
issues
d) Measures
and
variables
(What
were
the

major
independent
and
dependent
variables
and
how
were
they
manipulated
or
measured?)
V) Results
(What
are
they
major
sociological
findings
and/or
insights
presented
in
the
discussion
of
the
results?
Where
the

theory/theories
or
hypothesis/hypotheses
supported
or
not?)
VI) Provide
a
summary
or
concluding
paragraph
that
ties
everything
together.
(My
suggestion,
of
course,
is
that

provide
a
clear
and
concise
summary
of
the
research

you
reviewed)
