Suppose we randomly sample 8 students in their 1st year and record their final average at the end of year 1. We follow up with the same 8 people one year later, and record their final average at the end of year 2. The results are presented below: Final Average year 1:7673669575789693 year 2: 75 80 70 93 81908879 We want to test whether the grades have improved for these 8 students between year 1 and year 2. What is the observed value of the test statistic corresponding to the appropriate hypothesis test? What is the p-value corresponding to the observed value of the test statistic you computed? Give your answer to 3 decimal places. Based on the p-value, there is no indication that the final average has improved from year 1 to year 2. Select one: True False
