📝 Answered - To determine if his teaching method increases students' learning, a professor administers a pretest to his class at the beginning of the semester and then a posttest at the end of the semester. The results from 10 randomly chosen students are given below. Let Population 1 be the Pretest scores and Population 2 be the Posttest scores. | Test Scores | | --------- | -------- | | Pretest | Posttest | | 89 | 69 | | 92 | 72 | | 67 | 61 | | 98 | 91 | | 88 | 85 | | 98 | 84 | | 87 | 82 | | 67 | 76 | | 94 | 91 | | 71 | 62 | Step 1 of 2: Construct a $95 \%$ confidence interval for the true mean difference between the scores to determine if the teaching method increases students' knowledge of the course material. Round the endpoints of the interval to one decimal place, if necessary.
