Use the traditional method or P-value method as indicated. deviations 20 A researcher was interested in comparing the amount of time (in hours) spent watching television by women and by men. Independent simple random samples of 14 women and 17 men were selected, and each person was asked how many hours he or she had watched television during the previous week. The summary statistics are as follows. Women Men X1 = 12.5 hr X2 13.8 hr S1 = 3.9 hr S2 = 5.2 hr n1 = 14 n2 = 17 Use a 0.05 significance level to test the claim that the mean amount of time spent watching television by women is smaller than the mean amount of time spent watching television by men. Use the traditional method of hypothesis testing. a. State the hypotheses. b. Find the critical value(s). c. Compute the test statistic. d. Make the decision. e. Summarize the results.
