to find the mean, add all the numbers together and divide by the amount of numbers there is

89 + 92 + 97 + 81 + 96 = 455

455/5 = 91

91 is Andrew's mean score, and is your answer

hope this helps
First off, to find the mean, you need to add the numbers to each other, then divide the total by the amount of numbers you had.

In this case, your total after adding them together would be, 374, now divide that by the amount of different numbers you have, 5, and you will get your answer. The answer would be 74.8, or rounded up to 75.
