Question

The box plots show the average speeds, in miles per hour, for the race cars in two different races. Average Speeds of Cars in Race A 2 box plots. The number line goes from 120 to 170. For Race A, the whiskers range from 120 to 170, and the box ranges from 143 to 165. A line divides the box at 153. For Race B, the whiskers range from 125 to 165, and the box ranges from 140 to 150. A line divides the box at 145. Average Speeds of Cars in Race B

Answer 1

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:

For comparison, we need to analyze and compare both races data which are as follows

For Race A

Maximum range = 170 miles per hour

Minimum range = 120 miles per hour

First quartile ≈ 142 miles per hour

Median quartile ≈ 153 miles per hour

It comes from

`= (142\ miles + 165\ miles)/(2)`

= 153 miles

The Third quartile = 165 miles per hour

For Race B

Maximum range = 165 miles per hour

Minimum range = 125 miles per hour

First quartile ≈ 139 miles per hour

Median quartile = 145 miles per hour

It comes from

`= (139\ miles + 150\ miles)/(2)`

= 145 miles

The third quartile = 150 miles per hour

Hence, the last option is correct
