The box plots show the average speeds, in miles per hour, for the race cars in two different races

d) the median speed in race a is about 153 miles per hour, and the median speed in race b is about 145 miles per hour.

Explanation:

The whole question is written below:

The box plots show the average speeds, in miles per hour, for the race cars in two different races (figure attached) . Which statement compares the median speeds for the data in the two box plots?

a) the median speed in race a is about 142 miles per hour, and the median speed in race b is about 140 miles per hour.

b) the median speed in race a is about 120 miles per hour, and the median speed in race b is about 125 miles per hour.

c) the median speed in both races is about 165 miles per hour.

d) the median speed in race a is about 153 miles per hour, and the median speed in race b is about 145 miles per hour.

Firstly, let's explain how to read a box plot (as the shown in the second figure):

So, according to this, the median for race a (top plot) is between 150 and 155, and the median for race b (bottom plot) is 145.

Hence, among the given options the correct is:
