Answer 2

17.1

Explanation:

Given parameters:

Scores of Colins:

1, 25, 27, 3, 23, 25, 5, 9, 26, 27

A. Colin's mean score;

The mean is the sum of all values divided by the number of values in a given set;

Mean =
`(1 + 25 + 27 + 3 + 23 + 25 + 5 + 9 + 26 + 27)/(10)`

Mean =
`(171)/(10)`

Mean score = 17.1
