A. The range is 31.
B. The mode is 78
C. The median is 51
D. The mean is 52.​

Answer 1

D. The mean is 52.

Explanation:

Add all numbers in the set:

36+47+50+50+52+60+78= 416

Now, divide the sum by how many numbers are in the set; in this case, there are 8 numbers so:

416÷ 8= 52

Answer 2

D. The mean is 52.

Explanation:

In order to find the mean, you add up all of the numbers and then divide that answer by how many numbers there are.

43+50+60+36+47+52+78=416

416/8=52
