To find the mean of a data set, you add up all the numbers and then divide by the total number of numbers.
For the data set {13, 18, 13, 14, 13, 16, 14, 21, 13}:
Mean = (13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13) / 9
Mean = 135 / 9
Mean = 15
So, the mean of the data set is 15.

To find the range of a data set, you subtract the smallest number from the largest number.
The smallest number in the set is 13, and the largest number is 21.
Range = Largest number - Smallest number
Range = 21 - 13
Range = 8
So, the range of the data set is 8.

To find the mean medal count for Team U.S.A for the games shown, you add up all the medal counts and then divide by the total number of games.
For the given data:
Total medal count = 93 + 101 + 110 + 103 + 121 = 528
Mean medal count = Total medal count / Number of games
Mean medal count = 528 / 5
Mean medal count = 105.6
So, the mean medal count for Team U.S.A for the games shown is 105.6.
