Why each option

The mean is calculated by summing all numbers in a dataset and then dividing by the total count of numbers. For the given dataset (7, 2, 3, 3, 5), the sum is 20 and there are 5 numbers, resulting in a mean of 4.

A2

2 is the minimum value in the dataset, not the mean.

B3

3 is the mode and median of the dataset, but not the mean.

C4Correct

To calculate the mean, sum all the numbers in the dataset and divide by the count of numbers. For the given dataset (7, 2, 3, 3, 5), the sum is 7+2+3+3+5 = 20. There are 5 numbers, so the mean is 20 / 5 = 4.

D7

7 is the maximum value in the dataset, not the mean.
