Answer A, B1, and B2: A. The National Institute of Mental Health published an article stating that in any one-year period, approximately 9.5 percent of American adults suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, seven of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population. B. Researchers interested in lead exposure due to car exhaust sampled the blood of 52 police officers subjected to constant inhalation of automobile exhaust fumes while working traffic enforcement in a primarily urban environment. The blood samples of these officers had an average lead concentration of 124.32 µg/l and a SD of 37.74 µg/l; a previous study of individuals from a nearby suburb, with no history of exposure, found an average blood level…

QUESTION 3 A political candidate wants to enter a primary in a district with 100,000 eligible voters, but only if he has a good chance of winning. He hires a survey organization, which takes a simple random sample of 1600 voters. In the sample, 880 favor the candidate, so the percentage is 55%. This is good news but we need to understand the chance error. To find out the standard error, we need the SD of the box. But to compute this, we need the actual number of people out of 100,000 who would vote for him. We don't have this information. We'll use the bootstrap method which will use the sample information to approximate the population information to compute the SD of the box. Using the sample data, the SD of the box is estimated to be . Write your answer in the format 0.A where A is an integer. Use the short-cut formula for the SD. The standard error(SE) for the number of people who favor the candidate is . The SE for percentage is %. Write the answer in the format A.BC where…
do question 4, 5 and 6 only The new study claims that the probability of contracting the winter flu among vaccinated high school children is less than 0.5. Assume that p is the population proportion of vaccinated high school children who contract the flu. The appropriate framework to test the new study's claim is H0:p>0.5 vs H1:p<0.5 H0:p=0 vs H1:p≠0 H0:p=0 vs H1:p>0 H0:p=0.5 vs H1:p<0.5 Question 4 The new study takes a random sample of 14 vaccinated high school children. Let x be the number of children in the sample who contract the flu. The p-value for the test can be calculated from a Binomial distribution using P(X≤x). The maximum number of children who can contract the flu to give evidence against the null hypothesis in Question 3 at the 5% level is 1 2 3 5 Question 5 Suppose the actual population proportion of vaccinated high school children who contract the flu is 30%. For a random sample of 14 vaccinated high school children and based on your answer to Question 4,…
