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.
