Question
Test the claim that the mean GPA of night students is smaller than the mean GPA of day students at the .01 significance level.
The null and alternative hypothesis would be:
Ho: LN = HD Ho: pN = PD Ho:PN = PD Ho: UN = 4D Họ:pN = PD Họ: HN = HD
Hị: HN > uD H1: PN # PD H1: PN > PD H1: LN + 4D Hị : pN < PD H1: N < HD
The test is:
right-tailed left-tailed two-tailed
The sample consisted of 25 night students, with a sample mean GPA of 2.87 and a standard deviation of 0.03, and 50 day students, with a
sample mean GPA of 2.89 and a standard deviation of 0.04.
The test statistic is:
(to 2 decimals)
The critical value is:
(to 2 decimals)
Based on this we:
Reject the null hypothesis
O Fail to reject the null hypothesis
