Max- 55 Min -15 Q1 -20 Q2- 35 Q3- 40

1 What percent of runners run less than 40 miles a week?
2 How many runners run less than 20 miles a week

Answer 1

First, 10 is your minimum (the least)rather than 12, and 60 is your maximum (the most).

1. Q3 = 75th percentile

2. Q1 = 25th percentile

Q2 = 50th percentile or the median.

This is assuming that your quartile values are correct.

I hope this helps. Thanks for asking.
