The high school athletic director is asked if football players are doing as well academically as the other student athletes. We know from a previous study that the average GPA for the student athletes is 3.10. After an initiative to help improve the GPA of student athletes, the athletic director randomly samples 20 football players and finds that the average GPA of the sample is 3.18 with a sample standard deviation of 0.54. Is there a significant improvement? Use a 0.05 significance level. Hypothesis Step 1: Cleary state the null and alternative hypotheses. ALTERNATIVE HYPOTHESIS: ____3.18_________more than____3.10__________________ Hypothesis Step 2: Identify the appropriate significance level and confirm the test assumptions.
