A professor would like to test the hypothesis that the average number of minutes that a student needs to complete a statistics exam is equal to 45 minutes. The correct hypothesis statement would be:

H0: \\mu=45 H1: \\mu>45

H0: \\mu=45 H1: \\mu\ e45

H0: \\mu\ e45 H1: \\mu=45

H0: \\mu=45 H1: \\mu<45

Solution

H0: \\mu=45 H1: \\mu\ e45

because professor is not sure whether average number of minutes that a student needs to complete a statistics exam is equal to 45 minutes or not. It may be greater or less to 45 mins..
