Question Christine is the dean of students at a college. She is concerned about the average amount of sleep students in the pre-med program are getting. Christine makes an inquiry on whether students who are enrolled in the pre-med program are getting less sleep on average compared to pre-law students. The average number of hours of sleep per night for a random sample of 30 pre-med students and 30 pre-law students is recorded. Assume that the population variances of hours of sleep per night for pre-med students and for pre- law students are not equal and that the hours of sleep per night for both groups of students are normally distributed. Let the average number of hours of sleep per night for pre-med students be the first sample, and let the average number of hours of sleep per night for pre-law students be the second sample. She conducts a two-mean hypothesis test at the 0.05 level of significance, to test if there is evidence that pre-med students are getting less sleep than pre-law students. (a) Which answer choice shows the correct null and alternative hypotheses for this test? Select the correct answer below: = Ho #2: Ha, which is a two-tailed test. Ho HH2: Ha H H2, which is a right-tailed test.
