What would your conclusions be if the dean of students suspected that the mean number ofalcoholic drinks that students in the college consume in a typical week islower than the mean of U.S. college students in general? In other words, if this were a test of the hypotheses:

H0:=4.73H0:=4.73 drinks per week

Ha:<4.73Ha:<4.73 drinks per week

A group of 75 college students from a certain liberal arts college were randomly sampled and asked about the number of alcoholic drinks they have in a typical week. The file containing the data is linked below. The purpose of this study was to compare the drinking habits of the students at the college to the drinking habits of college students in general. In particular, the dean of students, who initiated this study, would like to check whether the mean number of alcoholic drinks that students at his college have in a typical week differs from the mean of U.S. college students in general, which is estimated to be 4.73. The following question uses the drinks data set.
