10.26 An independent-samples t test, "all inclusive resorts, and alcohol consumption: At some vacation destinations,"all-inclusive" resorts allow you to pay a flat rate and then eat and drink as much as you want. There has been concern about whether these deals might lead to excessive consumption of alcohol by young adults on spring break trips.You decide to spend your spring break collecting data on this issue. Of course, you need to take all of your friends on this funded research trip, because you need a lot of research assistants! You collect data on the number of drinks consumed in a day by people staying at all-inclusive resorts and by those staying at noninclusive resorts. Your data include the following: All-inclusive resort guests: 10, 8, 13 Noninclusive resort guests: 3, 15, 7 Conduct all six steps of an independent-samples t test. Be sure to label all six steps. a. b. Report the statistics as you would in a journal article. Is there a shortcut you could or did use to compute your hypothesis test? (Hint: There are equal num- bers of participants in the two groups.) C. d. Calculate the 95% confidence interval. e. State in your own words what we learn from this confidence interval. f. Express the confidence interval, in a sentenée, as a 111argin of error. g. Calculate the appropriate measure of effect size. h. Based on Cohen's conventions, is this a small, medium, or Lurge effect size Why is it useful to have this intormation in addition t the results of t hypothesis test?
