A skeptical paranormal researcher claims the proportion of Americans that have seen a UFO, p,
is less than 1 in every one thousand. Identify the type 2 error for the test.

Solution
Type II error is when you do not reject the null hypothesis even though it is false.
Ho: p = 1/1000 H1: p < 1/1000 (the researches claim) In this example the type II error would be
finding that the proportion of Americans that have seen a UFO is 1/1000 or higher when in fact,
the true proportion is less than 1 in 1000..

A simple random sample of 1000 American adults found that the average number of hours spent
watching television during a typical week was 13.8. A simple random sample of 500 Canadians
yielded an average of 12.5 hours per week of television viewing. Assume that the American and
Canadian distributions for weekly television, viewing times have the same standard deviations.
The sampling variability associated with the sample means (described above) is
A.) smaller for the sample of Canadians, since the population of Canada is less than half that of
the United States.
B.) larger for the sample of Canadians because the sample size is smaller.
C.) smaller for the sample of Canadians, because their population is smaller.
D.) larger for the sample of Canadians, since Canadian citizens are more widely dispersed
throughout their country than American citizens are in the United States. Hence, Canadians have
more variable views.

A set of waveforms applied to two D flip-flops is shown in Figure 4-.pdfagrawalsales2
A set of waveforms applied to two D flip-flops is shown in Figure 4-56. These waveforms are
applied to the flip-flops shown along with the values of their timing parameters.
(a) List the time(s) at which there are timing violations in signal D1 for flip-flop 2.
(b) List the time(s) at which there are timing violations in signal D2 for flip-flop 2.
Solution
flip flop 1 is a positive edge triggered flop.
The inputs should be seen at the rising edge of the clock
for signal D1, at the fourth rising edge i.e t = 28ns, violation occurs.
D1 is rising at the same edge, it should be stable for Ts = 1ns before and Th =0.5ns after the
edge.
2)
flipflop 2 is a negative edge triggered.
At second negative edge i.e t = 16ns and third negative edge i.e t = 24ns, D2 signal viloates the
timing requirements of flop2.

A short quiz has two true/false questions and one multiple choice question with four choices. A

Solution
The events are independent, so P(A and B) = P(A)*P(B) --- P(2 correct on true-

A share of common stock has just paid a dividend of $2.00 (D0 = 2.00.pdfagrawalsales2
A share of common stock has just paid a dividend of $2.00 (D0 = 2.00). The long-term growth
rate for this stock is 15% (g = .15) and investors require a 19% return (r = .19). What is the price
of the stock today?
Solution
Price of stock = D0 (1+g) /(R- g)

If the variance is 4, sigma is the sqrt(4) = 2 z = (x - mu) / sigma z = (31 - 28) / 2 z =

I did not use the standard error of the sampling distribution [ (x - )/(/n) ] because that is only used

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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
