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

Which statement compares the median speeds for the data in the two box plots?
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.
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.
The median speed in both races is about 165 miles per hour.
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.

Answer 1

B. The speeds in race A are likely to be near 153 mph and the speeds in race B are likely to be near to 145 mph.

Explanation:

Answer 2

The correct option is;

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:

Here we have the box plot which shows the following 5 values

Race A

Maximum = 170 miles per hour

Minimum = 120 miles per hour

1st quartile ≈ 142 miles per hour

Median or 2nd quartile ≈ 153 miles per hour

3rd quartile = 165 miles per hour

Race B

Maximum = 165 miles per hour

Minimum = 125 miles per hour

1st quartile ≈ 139 miles per hour

Median or 2nd quartile = 145 miles per hour

3rd quartile = 150 miles per hour

Therefore, the correct option is as follows;

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.
