10.24 An independent-samples t test and getting ready for a date: In an example we sometimes use in our statistics classes, several semesters' worth of male and female students were asked how long, in minutes, they spend getting ready for a date. The data reported here reflect the actual means and the approximate standard deviations for the actual data from 142 students. Men: 28, 35, 52, 14 Women: 30, 82, 53, 61 a. Conduct all six steps of an independent-samples t test. Be sure to label all six steps. b. Report the statistics as you would in a journal article. C. Calculate the 95% confidence interval. d. Calculate the 90% confidence interval. e. How are the confidence intervals different from each other? Explain why they are different. f. Calculate the appropriate measure of effect size. 8 Based on Cohen's conventions, is this a small, medium, or large effect size? h. Why is it useful to have this information in addition to the results of a hypothesis test?
