Test the claim that the mean GPA of night students is smaller than 2.4 at the 0.10 significance level. The null and alternative hypothesis would be: Ho: u 2 2.4 Ho:p > 0.6 Ho:p < 0.6 Ho:u < 2.4 Ho:p = 0.6 Ho: = 2.4 H1 : µ < 2.4 H1:p< 0.6 H1:p > 0.6 H1: µ > 2.4 H1:p# 0.6 H1:µ + 2.4 %3D The test is: right-tailed left-tailed two-tailed Based on a sample of 45 people, the sample mean GPA was 2.36 with a standard deviation of 0.08 The p-value is: (to 2 decimals) Based on this we: O Fail to reject the null hypothesis O Reject the null hypothesis
