Answer:

D. 14.32

Step-by-step explanation:

The mean μ is 33.

The (x minus μ) squared are 361, 49, 49, 361 respectively.

So that the SD = \sqrt{\frac{820}{4}} \approx 14.31782...

Median = (7+7)÷2 = 7

The mean is the averagw value in a data set. You find it be adding all the numbers and then divide the answer by the number of numbers.
