The arithmetic mean is defined as the sum of the individual members of the population divided by the number of members. The mean score for the nine members of Mt. Dexter's team is (15 + 20 + 19 + 20 + 16 + 20 + 14 + 18 + 17) / 9 = 159/9 = 17 and 2/3 (17.666 repeating)
4 The formula is sum of scores divided by number of scores.

You add the scores together and then divide by the number of scores. So if you rolled a dice and your scores were, 3, 5, 2, and 6 You would add these together, getting 16, and then you would divide this by 4 (because you have 4 scores) and so your mean would be 4 (16/4=4) sum of scores / number of scores = mean. Hope this helps.

68% of the scores are within 1 standard deviation of the mean -80, 120 95% of the scores are within 2 standard deviations of the mean -60, 140 99.7% of the scores are within 3 standard deviations of the mean -40, 180
sum of scores: 24 mean of scores : 24/4 = 6 squared deviations from the mean: 9, 4,4,9 sum of these: 26 sample variance: 26/4 = 6.5
