Answer 2

Answer:

17.1

Step-by-step 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 = $\frac{1 + 25 + 27 + 3 + 23 + 25 + 5 + 9 + 26 + 27}{10}$

  Mean = $\frac{171}{10}$

 Mean score = 17.1
