Test the claim that the mean GPA of night students is significantly different than 2 at the 0.1 significance level. The null and alternative hypothesis would be: Ho : µ = 2 Ho:H = 2 Ho:p = 0.5 Họ: p = 2 Ho:p= 0.5 Ho:p = 0.5 H:µ +2 H1:p > 2 H1:p > 0.5 H, : µ < 2 H1:p < 0.5 H1:p# 0.5 The test is: right-tailed two-tailed left-tailed Based on a sample of 80 people, the sample mean GPA was 2.02 with a standard on of 0.05 The test statistic is: (to 2 decimals) The positive critical value is: (to 2 decimals) Based on this we: O Reject the null hypothesis O Fail to reject the null hypothesis
