Question
Test the claim that the mean GPA of night students is significantly different than the mean GPA of
day students at the 0.05 significance level.
The null and alternative hypothesis would be:
Ho:PN 2 PD Ho:PN = PD Ho: PN < PD Ho:UN HD Ho:uN 2 PD Ho: HN = HD
H1:PN < PD H:PN # PD H1:PN > PD H1:UN > HD H1:uN < HD H1:UN # HD
The test is:
two-tailed right-tailed left-tailed
The sample consisted of 75 night students, with a sample mean GPA of 2.49 and a standard
deviation of 0.07, and 75 day students, with a sample mean GPA of 2.45 and a standard
viation of
0.02.
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
