Answer:

mean = 23

median = 22.50

mode = 20

range = 7.5

Explanation:

mean is the total / n

total = 20+20+22.50+25+27.50 = 115

n= 5

mean = 115/5 = 23

median you'll arrange the numbers in ascending order and pick the middle one and its 22.50

20, 20, [22.50], 25, 27.50

mode is the number that is repeated mostly and it was 20.

range is max - min

max is 27.50

min is 20

range = 27.50 - 20

range = 7.50
