Answer Details
To find the mean score, we need to calculate the sum of all the scores, and then divide it by the total number of scores.
The scores are given as 4, 7, 8, 11, 13, 8 with corresponding frequencies of 3, 5, 2, 7, 2, 1 respectively.
So, the sum of all the scores is:
4 × 3 + 7 × 5 + 8 × 2 + 11 × 7 + 13 × 2 + 8 × 1 = 12 + 35 + 16 + 77 + 26 + 8 = 174
The total number of scores is:
3 + 5 + 2 + 7 + 2 + 1 = 20
Therefore, the mean score is:
mean = sum of scores / total number of scores = 174 / 20 = 8.7
So, the answer is.
