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. a. Is this a test of one mean or proportion? b. State the null and alternative hypotheses. HO: c. Is this a right-tailed, left-tailed, or two-tailed test? d. What symbol represents the random variable for this test? e. In words, define the random variable for this test. f. Calculate the following: i. x = На: ii. n= lii. p' = g. Calculate ox = h. State the distribution to use for the hypothesis test. i. Find the p-value. j. At a pre-conceived a = 0.05, what is your: i. Decision: ii. Reason for the decision: iii. Conclusion (write out in a complete sentence): Show the formula set-up.

A health statistics agency in a certain country tracks the number of adults who have health insurance. Suppose according to the agency, the uninsured rates in a recent year are as follows: 5.2% of those under the age of 18, 12.7% of those ages 18-64, and 1.3% of those 65 and older do not have health insurance. Suppose 22.4% of people in the county are under age 18, and 61.9 % are ages 18-64. (a) What is the probability that a randomly selected person in this country is 65 or older? 157 (b) Given that a person in this country is uninsured, what is the probability that the person is 65 or older?

An issue of Time Style and Design reported on a poll conducted on the shopping habits of wealthy Americans. A total of 603 interviews were conducted among a national sample of adults with household incomes of at least $150,000. Of the adults interviewed, 410 said they had purchased clothing, accessories or books online in the past year. We want to understand the percentage of wealthy Americans who shop online. Do the data provide sufficient evidence to say that the majority (more than 50%) of wealthy Americans shop online at the 5% significance level? a. What are n, x, n-x and ??̂? b. State the null and alternative hypotheses. c. What is the value for the test statistic z0? d. Find the p-value. e. Do the data support that (more than 50%) of wealthy Americans shop online?
2. In a study of parents' feelings about a required course in consumer education taught to their children, a random sample of 360 parents are classified according to whether they have one, two or more children in the school system, and also whether they feel that the course is poor, adequate or good. The results are shown in the table to the right. Test at the 0.05 level of significance whether there is a relationship between parents' reaction to the course and the number of children they have in the school system.
