Question
Test the claim that the mean GPA of night students is significantly different than 3.5 at the 0.1 significance level. The null and alternative hypothesis would be: Ho: µ = 3.5 Ho: µ = 3.5 Ho:p = 0.875 Ho:µ = 3.5 Ho:p= 0.875 Ho:p=0.875 H1: µ < 3.5 H1: µ # 3.5 H1:p < 0.875 H1:µ > 3.5 H1:p# 0.875 H1:p > 0.875 The test is: two-tailed right-tailed left-tailed Based on a sample of 70 people, the sample mean GPA was 3.46 with a standard deviation of 0.04 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
