QUESTION 28 Most professional health societies recommend that college students should sleep, on average, 7 hours a night. A random sample of 15 Zu students is selected and their typical sleeping times are recorded. We are interested in testing whether the mean sleeping time of ZU students falls below the recommended time. Assume that the population of sleeping is strongly right skewed. Which test would be appropriate for this problem? Neither one-sample z-test nor one-sample t-test Either one-sample z-test or one-sample t-test One-sample t-test One-sample z-test
