Answer: Mean = 89.67
Explanation:
Step 1:
Calculate the sum of integers, then divide by the number (N) of scores:
Sum of scores = 538
538 ÷ 6 = 89.67
Step 2:
89.67 - 85 = 4.67
89.67 - 86 = 3.67
89.67 - 84 = 5.67
89.67 - 88 = 1.67
99 - 89.67 = 9.33
96 - 89.67 = 6.33
Step 3:
Avg = Sum / N
4.67 + 3.67 + 5.67 + 1.67 + 9.33 + 6.33 = 31.34
Avg = 31.34 / 6 = 5.223
