Fayech University claims that the mean GPA of night students is approximately normally distributed with mean 3.3 with a population standard deviation of 0.04. We wish to test the claim that the mean GPA of night students is significantly different than 3.3 at the 0.05 significance level.  Based on a sample of 55 people, we find the sample mean GPA was 3.33. The null and alternative hypothesis would be: [a] Type the letter of the correct option in the box above. A B C D E F The test is: [b] Type the letter of the correct option in the box above. A B C two-tailed left-tailed right-tailed The test statistic is [d] (to 2 decimals) The critical value is:  [e] (to 2 decimals) Draw a picture of this graph on your scratch paper.  I will grade the graph after you upload your work. [c] Based on this we [f] A B Fail to reject the null hypothesis Reject the null hypothesis
