You are testing the claim that the mean GPA of night students is less than the mean GPA of day students. You sample 45 night students, and the sample mean GPA is 2.99 with a standard deviation of 0.68 You sample 30 day students, and the sample mean GPA is 2.64 with a standard deviation of 0.62 Calculate the test statistic, rounded to 2 decimal places
Test the claim that the mean GPA of night students is larger than the mean GPA of day students at the 0.005 significance level. The null and alternative hypothesis would be: Ho: PNPD Ho:N HD Ho: HN 2 HD Ho: N = HD Ho: PN 2 PD Ho PN S PD H₁ PNPD H₁ HN > HD H₁N <HD H₁: HN HD H₁ PN <PD H₁: PN > PD O The test is: left-tailed two-tailed right-tailed The sample consisted of 50 night students, with a sample mean GPA of 2.22 and a standard deviation of 0.02, and 50 day students, with a sample mean GPA of 2.19 and a standard deviation of 0.08. The test statistic is: (to 2 decimals) The p-value is: Based on this we: O Fail to reject the null hypothesis O Reject the null hypothesis (to 2 decimals)
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: HND Ho: PN PD Ho: HN = HD H₁ HN HD H₁ PN > PD H1 HN HD Hit O The test is: right-tailed two-tailed left-tailed O The sample consisted of 45 night students, with a sample mean GPA of 3.39 and a standard deviation of 0.03, and 45 day students, with a sample mean GPA of 3.4 and a standard deviation of 0.06. (to 2 decimals) The test statistic is: The p-value is: Based on this we: Ho: PN 2 PD Ho: PN = PD Ho: HN ZHD H₁:PN <PD H₁ PN PD H₁: HN <HD O Fail to reject the null hypothesis O Reject the null hypothesis (to 2 decimals)
