Test the claim that the mean GPA of night students is significantly different than 2.4 at the 0.2 significance level. The null and alternative hypothesis would be: H0:p=0.6H0:p=0.6 H1:p<0.6H1:p<0.6 H0:p=0.6H0:p=0.6 H1:p>0.6H1:p>0.6 H0:μ=2.4H0:μ=2.4 H1:μ≠2.4H1:μ≠2.4 H0:μ=2.4H0:μ=2.4 H1:μ>2.4H1:μ>2.4 H0:p=0.6H0:p=0.6 H1:p≠0.6H1:p≠0.6 H0:μ=2.4H0:μ=2.4 H1:μ<2.4H1:μ<2.4 The test is: right-tailed left-tailed two-tailed Based on a sample of 60 people, the sample mean GPA was 2.37 with a standard deviation of 0.03 The test statistic is:  (to 2 decimals) The positive critical value is:  (to 2 decimals) Based on this we: Reject the null hypothesis Fail to reject the null hypothesis I dont understand this.
