D. 20, 20, 21, 22, 22

Answer:

Step-by-step explanation:

Required

Which list has a mean of 21 and median of 20

Each of the list have 5 numbers and they've all been sorted.

The median is the number at the 3rd position (i.e. the middle number)

So, list C and D are out because they do not have a median of 20.

Next, calculate the mean of lists A and B

$\bar x = \frac{\sum x}{n}$

A. 18, 20, 20, 22, 25

$\bar x = \frac{18 + 20 + 20 + 22 + 25}{5}$

$\bar x = \frac{105}{5}$

$\bar x = 21$

B. 20, 20, 20, 25, 25

$\bar x = \frac{20 + 20 + 20 + 25 + 25}{5}$

$\bar x = \frac{110}{5}$

$\bar x = 22$

Only list A has a median value of 20 and a mean value of 21
