Answer:
54.1428
Step-by-step explanation:
To find the mean is to find the average of a group of numbers. To find it you add up all of the numbers in the set, and then divide by the number of numbers in the set. 63 + 54 + 49 + 62 + 48 + 53 + 50 = 379. Because the set has seven numbers in the set, you divide 379 by 7. This will give you the mean or average, which is 54.1428
