Test the claim that the mean GPA of night students is larger than the mean GPA of day students at the .005 significance level. The null and alternative hypothesis would be: Ho:PN = PD Ho:HN = HD Ho:PN = PD Ho:HN = HD Ho:HN = HD Ho:PN = PD H1:PN > PD H:HN < HD H1:PN # PD H1:HN HD H1:HN > HD H:PN < PD The test is: left-tailed right-tailed two-tailed The sample consisted of 25 night students, with a sample mean GPA of 2.48 and a standard deviation of 0.07, and 30 day students, with a sample mean GPA of 2.46 and a standard deviation of 0.05. The test statistic is: (to 2 decimals) The critical value is: (to 2 decimals) Based on this we: OReject the null hypothesis Fail to reject the null hypothesis
