Given the weight of 7 fish:

15, 16, 15, 13, 19, 20, and 21 pounds.

Determine the mean weight of the fishes.

Mean = Summation of values/Number of Values

Number of Values ( n ) = 7

Solution:

Add the given weight of the 7 fishes, then divided the sum by 7.

Mean = (15 + 16 + 15 + 13 + 19 + 20 + 21)/7

Mean = 119/7

Mean = 17

Final answer:

The Mean weight of the fishes is 17.
