The heights of young women in AZ are Normally distributed with unknown mean. A random sample of 44 AZ women had a sample mean of xbar = 68.5 inches and sample standard deviation of s = 2.4 inches. Do we have evidence that the true mean (mu) is greater than 67 inches? Test the appropriate hypotheses, make your conclusion based on the critical value method. a. State the null and alternative hypotheses. b. Compute the observed value of the test statistic. c. Give the critical value(s) (t or z as appropriate), conclusion (use alpha = 0.01), and interpretation. 2. Suppose the p-value for a test is 0.034. Would you reject H0 at the 5% level of significance? (A) Yes (B) No

    For a sample of n = 20 women aged 18 to 29, responses to the question “How tall would you like to be?" are recorded along with actual heights. In the sample, the mean desired height is 66.7 inches, the mean actual height is 64.9 inches, and the sample mean difference (desired - actual) is 1.8 inches. The sample standard deviation of the differences is 2.1 inches. Researchers hypothesize that, on average, women desire to be taller than they actually...
