Question: Suppose that a one-sample t-test of H0: μ = 0 versus Ha: μ - 0 results in a test statistic of t = 0.65 with df = 14. Suppose that a new study is done with n = 150, and the sample mean and standard deviation turn out to be exactly the same as in the first study.
a. What conclusion would you reach in the original study, using a = .05?
b. What conclusion would you reach in the new study, using a = .05?
c. Compare your results in parts (a) and (b) and comment.
Test the hypothesis that the median ?uoride level for this city is 0.90 against the alternative that the median is different from 0.9 at α = 0.01, using (a) the large sample sign test, and (b) the Wilcoxon signed rank test. Interpret the results.
