Sagot :
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.
