Suppose again that m = 2, but that now the p-values for the two tests are negativelycorrelated, so that if one is large then the other will tend to be small. How does the family-wiseerror rate associated with these m = 2 tests qualitatively compare to the case of independenttests?Hint: First, suppose that whenever one p-value is less than a, then the other will be greaterthan a. In other words, we can never reject both null hypotheses.They are the same.FWER is greater for negatively correlated tests than for independent testsFWER is smaller for negatively correlated tests than for independent tests.

For a certain knee surgery, a mean recovery time of 9 weeks is typical. With a new style of physical therapy, a researcher dlaims that the mean recovery time, ET u, is less than 9 weeks. In a random sample of 84 knee surgery patients who practiced this new physical therapy, the mean recovery time is 8.9 weeks. Assume that the population standard deviation of recovery times is known to be 0.9 weeks. Is there enough evidence to support the claim that the mean recovery time of patients who practice the new style of physical therapy is less than 9 weeks?

Under what circumstances is a t statistic used instead of a z-score for a hypothesis test? Justin wants to know whether a commonly prescribed drug does improve the attention span of students with attention deficit disorder (ADD). He knows that the mean attention span for students with ADD who are not taking the drug is 2.3 minutes long. His sample of 12 students taking the drug yielded a mean of 4.6 minutes. Justin can find no information regarding σx , so he calculated s2x =1.96. Determine the critical region using a one-tailed test with alpha = .05. Conduct the hypothesis test (Do the math and compare the t-critical and t-obtained values). State your conclusions in terms of H0 (Should you reject the H0 or fail to reject/accept the H0). Based on your analysis, is there a relationship between the drug and attention span?
