Answer 1

Using the mean concept, it is found that the correct option is given as follows:

A

Football Team Mean: 75"

Basketball Team Mean: 77"

Difference: 2"

What is the mean?

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

For the football team, considering the 11 players, it is given by:

M = (72 + 80 + 74 + 76 + 76 + 79 + 78 + 73 + 79 + 68 + 70)/11 = 75"

For the basketball team, it is given by:

M = (78 + 79 + 79 + 80 + 76 + 77 + 77 + 76 + 77 + 74 + 74)/11 = 77"

The difference is the subtraction of the means, hence:

D = 77" - 75" = 2"

Thus option A is correct.
