![Test the claim that the mean GPA of night students is smaller than the mean GPA of day students at
the 0.025 significance level.
The null and alternative hypothesis would be:
Ho: HN S HD Ho:PN 2 PD Ho:PN = PD Ho: HN= HD Ho:PN < PD Ho:HNN HD
H1: HN > HD H1:PN < PD H1:PN # PD H1:HN # HD H1:PN > PD H1:UN < µD
The test is:
two-tailed right-tailed left-tailed
The sample consisted of 30 night students, with a sample mean GPA of 2.56 and a standard
deviation of 0.08, and 30 day students, with a sample mean GPA of 2.59 and a standard deviation of
0.06.
The test statistic is:
(to 2 decimals)
The p-value is:
(to 2 decimals)
Based on this we:
O Reject the null hypothesis
O Fail to reject the null hypothesis
