Fayech University claims that the mean GPA of night students is approximately normally distributed with mean 3 with a population standard deviation of 0.08. We wish to test the claim that the mean GPA of night students is significantly different than 3 at the 0.1 significance level.  Based on a sample of 25 people, we find the sample mean GPA was 2.97. 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
