Answer 2

The correct answer: 1.2

Explanation:

It says Enzo's mean score is 44. You subtract each of his scores from 44 which should leave you with the follow:

5, 3, 2, 6, 6 = 22

You divide this by the total number of attempts (5).

21/5 = 4.4

You do the same thing for Zahra's score.

Zahra's mean score is 38.

1, 5, 7, 8, 7 = 28

You divide this by the total number of attempts (5).

28/5 = 5.6

You subtract your means:

5.6-4.4 = 1.2
