a. 76
b. 72
c. 73
d. 67
The mean score is 72.
To find the meanscore, you need to add up all the scores and then divide the sum by the number of scores. In this case, we have 10 scores, so the mean score is the sum of these scores divided by 10.
Adding up the scores, we have: 71 + 67 + 67 + 72 + 76 + 72 + 73 + 68 + 72 + 72 = 720
Dividing the sum by 10, we get the mean score: 720 / 10 = 72
