Question

Find the mean of the data set. If necessary, round to the nearest tenth. 8, 2, 8, 2, 2, 8, 8, 8, 2, 8

Answer 1

To find the mean of the data set, we need to add up all of the numbers and then divide by the total number of numbers.

8 + 2 + 8 + 2 + 2 + 8 + 8 + 8 + 2 + 8 = 54

There are 10 numbers in the data set, so we divide the sum by 10:

54 / 10 = 5.4

Therefore, the mean of the data set is 5.4 (rounded to the nearest tenth).
