Fаyech University clаims thаt the mean GPA оf night students is apprоximately nоrmally distributed with mean 3 with a population standard deviation of 0.07. We wish to test the claim that the mean GPA of night students is significantly different than 3 at the 0.05 significance level. Based on a sample of 50 people, we find the sample mean GPA was 2.96. 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
