Test the claim that the mean GPA of night students is smaller than the mean GPA of day students at the 0.01 significance level. The null and alternative hypothesis would be: Ho: PN = PD Ho: N ≤ HD H1:PN PD H₁: N > HD The test is: right-tailed two-tailed left-tailed The test statistic is: Ho: PN PD Ho: N = HD Ho: PNZ PD H₁: PN > PD H₁: NMD H₁: PN < PD The sample consisted of 75 night students, with a sample mean GPA of 2.89 and a standard deviation of 0.08, and 75 day students, with a sample mean GPA of 2.9 and a standard deviation of 0.07. The p-value is: Based on this we: O Reject the null hypothesis Fail to reject the null hypothesis (to 2 decimals) Ho: HN ZHD H₁: UN < HD (to 2 decimals)
