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 B
Which correctly describes the consistency of the speeds of the cars in the two races?
The speeds in race A are likely to be near 170 mph and the speeds in race B are likely to be near to 165 mph.
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.
The speeds in race A are likely to be near 120 mph and the speeds in race B are likely to be near to 125 mph.
The speeds in race A are likely to be near 145 mph and the speeds in race B are likely to be near to 153 mph.

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.

Step-by-step explanation:

Hello!

Boxplots in attachment, upper box plot corresponds to Average Speeds of Cars in Race A and the bottom box plot corresponds to Average Speeds of Cars in Race B.

Concerning the boxplot for Race A

The range of speed od the race is R= max-min = 170 - 120= 50

The 1st Quantile is ≅ 142

The 2nd Quantile is ≅ 153

The 3rd Quantile is 165

The IQD: 165-142≅ 23

Concerning the boxplot for Race B

The range of speed od the race is R= max-min = 165 - 125= 40

The 1st Quantile is ≅ 139

The 2nd Quantile is = 145

The 3rd Quantile is 150

The IQD: 150 - 139 ≅ 11

The middle fifty of the data are set around the mean (to resolve this exercise I'll consider it to be near the Median for coth races)

which means that the mean speed for race A is around 153 and the mean speed for race B is around 145.

The mean represents the expected value of a data set, i.e. it is the value around wich most of the data usually lies.

With this in consideration, the best description is:

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.

I hope this helps!

The answer happens to be B, as I am taking the test right now.
