To find the mean score, you need to add up all the scores and divide by the total number of scores.
Total score = 72 + 80 + 74 + 68 + 65 + 66 + 72 + 70 + 65 + 80 + 75 = 747
Number of scores = 11
Mean score = Total score / Number of scores = 747 / 11 ≈ 67.9
Rounded to the nearest tenth, Jennifer's mean score is 67.9, which is closest to option A, 71. Therefore, the answer is A) 71.
72, 80, 74, 68, 65, 66, 72, 70, 65, 80, 75
