Dr. Moo conducted a research project in which she compared the impact of two types of therapy (pizza therapy and chocolate therapy) and gender on college students’ happiness. How many null hypotheses did she have, and how would you write them?
Suppose you want to find out how many people support Policy X. A standard polling approach is to just ask N many people whether or not they support Policy X, and take the fraction of people who say yes as an estimate of the probability that any one person supports the policy. Suppose that the probability someone supports the policy is p, which you do not know. Let îy be the number of people polled who supported the policy, divided by the total number of people polled N. However, a problem with polling is whether or not people are willing to answer honestly. If a question might be viewed as shameful or embarrassing (about politics, sexual activity, or whatever people are sensitive about), they may be reluctant to answer honestly. A potential solution to this is the following: suppose that 'YES' is the embarrassing or socially shameful answer; give the people you are polling the following instructions: flip a coin privately, and if it comes up heads answer honestly, but if it comes up…
Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 488 were in favor, 399 were opposed, and 123 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 123 subjects who said that they were unsure, and use a 0.10 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test.

Joe Biden (Democrat) will be running for President of the United States in 2020. His campaign is continually, among other things, wanting to estimate the percentage of Americans who will vote for him. a) How many Americans should be sampled to estimate the percentage of those who will vote for Joe Biden if his campaign wants to be 95% confident that the margin of error is no more than 2%? The last poll found that 49% of Americans said they will vote for Biden.
Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 481 were in favor, 396 were opposed, and 117 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 117 subjects who said that they were unsure, and use a 0.05 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim?

Mitt Romney was a presidential candidate in the Novem-ber 2012 U.S. presidential elections and he is a Mormon. The Public Religion Research Institute, during its 2011American Values Survey, asked 1019 random Americansif they would be comfortable with a Mormon serving asPresident. Fifty three percent reported that they wouldbe somewhat or very comfortable with this. Which ofthe following hypotheses should we test to determinewhether the majority of Americans would be somewhator very comfortable with a Mormon serving as president?A) H0 : p = 0.50 HA: p ≠ 0.50B) H0 : p = 0.50 HA: p 6 0.50C) H0 : p = 0.50 HA: p 7 0.50D) H0 : p = 0.53 HA: p 7 0.53E) H0 : pn = 0.53 HA: pn ≠ 0.53(Source: http://publicreligion.org/research/2011/11/2011-american-values-survey/)

The Diversity, Equity, and Inclusion (DEI) office of a major multinational bank is investigating the process used to make recent hires for financial analysts. The office knows that exactly 10% of all applications were from minority candidates and that exactly 8% of the open positions were filled by members of a minority. For the investigation, the DEI office will take a random sample of 900 applications. Let p be the proportion of minority applicants in the sample. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p. 0 (b) Find the standard deviation of p. 0 (c) Compute an approximation for P(p ≤0.08), which is the probability that there will be fewer minority applicants in the sample than were hired by the bank. Round your answer to four decimal places. 0 X Ś
2) The Director of NJ Division of Elections wants to determine the proportion of college students who vote in elections. In a random sample of 250 college students, it was found that 120 students voted in the last election. Construct a 95% confidence interval for the population proportion of college students who vote in elections. Interpret your results.
A university has decided to introduce the use of plus and minus grading as long as there is evidence that 60% of the faculty is in support of this change. Write an appropriate null hypothesis and alternate hypothesis to test if the proportion is greater than 60%.
Minnesota had the highest turnout rate of any state for the 2016 presidential election.† Political analysts wonder if turnout in rural Minnesota was higher than turnout in the urban areas of the state. A sample shows that 627 of 836 registered voters from rural Minnesota voted in the 2016 presidential election, while 414 out of 575 registered voters from urban Minnesota voted. (a) Formulate the null and alternative hypotheses that can be used to test whether registered voters in rural Minnesota were more likely than registered voters in urban Minnesota to vote in the 2016 presidential election. (Let p1 = the population proportion of voters in rural Minnesota who voted in the 2016 election and p2 = the population proportion of voters in urban Minnesota who voted in the 2016 election.) (b) What is the proportion of sampled registered voters in rural Minnesota that voted in the 2016 presidential election? (c) What is the proportion of sampled registered voters in urban…
