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:N HD Ho: PN ≤ PD Ho: PN = PD H₁: HN> HD H₁:PN > PD H₁: PN PD The test is: left-tailed right-tailed two-tailed The sample consisted of 80 night students, with a sample mean GPA of 2.48 and a standard deviation of 0.05, and 80 day students, with a sample mean GPA of 2.49 and a standard deviation of 0.04. The test statistic is: (to 2 decimals) The p-value is: Based on this we: Ho: N 2 HD Ho: PN 2 PD Ho: N = PD H₁N <HD H₁ PN <PD H₁ HN #UD Fail to reject the null hypothesis Reject the null hypothesis (to 2 decimals)
