Test the claim that the mean GPA of night students is significantly different than 3.3 at the 0.2 significance level. The null and alternative hypothesis would be: Ho:p<0.825 Ho:p 0.825 Ho:p < 3.3 Ho:p 0.825 Ho:p 2 3.3 Ho: p 3.3 H1:p > 0.825 H1:p <0.825 H1:p> 3.3 H:p 0.825 H:p < 3.3 H:p# 3.3 The test is: right-tailed two-tailed left-tailed Based on a sample of 80 people, the sample mean GPA was 3.33 with a standard deviation of 0.04 The p-value is: (to 2 decimals) Based on this we: Reject the null hypothesis Fail to reject the null hypothesis
