![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: N= μD Ho: μN = μD Ho: PN = PD
H₁ UND H₁ UND H₁: PNPD
O
The test is:
right-tailed left-tailed two-tailed o
The sample consisted of 25 night students, with a sample mean GPA of 2.78 and a standard deviation of
0.04, and 65 day students, with a sample mean GPA of 2.76 and a standard deviation of 0.08.
The test statistic is:
Ho: μN = μD Ho: PN = PD Ho: PN = PD OF
H₁N<D H₁: PN PD H₁: PNPD
The positive critical value is:
