Answer:
mean = 76.4
median = 72
Explanation:
to find the mean (the average) you add all the numbers given together then divide by how many numbers were there
70+72+99+72+69=382
382/5=76.4
to find the median you go from smallest to largest trying to find the middle
69,70,72,72,99
70,72,72
72
i believe that the 72 reflects better on the grades he gets because there is only one grade over a 76 and most of his grades are closer to the 72
