Your friend finds the mean and median of the data set: 40, 38, 62, 70, 56, 41, 58, 48, 60, 45. Your friend says that the mean and median are both 52. Is your friend correct? If not, find the correct answer. (1 point)

Answer 1

To check if your friend is correct, let's first find the mean and median of the data set.

Mean:
(40 + 38 + 62 + 70 + 56 + 41 + 58 + 48 + 60 + 45) / 10
(508) / 10
= 50.8

Median:
First, let's put the numbers in order:
38, 40, 41, 45, 48, 56, 58, 60, 62, 70

Since there are 10 numbers, the median will be the average of the two middle numbers:
(48 + 56) / 2
104 / 2
= 52

Therefore, your friend was incorrect. The correct answers are:
Mean = 50.8
Median = 52
