Answer:
mean = 23
median = 22.50
mode = 20
range = 7.5
Step-by-step 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
