The histograms show the ages of people riding two rides at an amusement park. Describe the shape of each distribution. Which ride has younger riders?

• Ride A is skewed left, and Ride B is skewed right. Ride B has younger riders.

The frequency table shows the gas mileages of several vehicles. What is the most appropriate measure to describe the center? to describe the variation? Mileage (miles per gallon): 15–19 (12), 20–24 (8), 25–29 (6), 30–34 (4), 35–39 (2).

• The median is the most appropriate measure to describe the center, and the range or interquartile range is appropriate to describe the variation.

• The mean is the most appropriate measure to describe the center, and the standard deviation is appropriate to describe the variation.

• The mode is the most appropriate measure to describe the center, and the variance is appropriate to describe the variation.

• The mean is the most appropriate measure to describe the center, and the range is appropriate to describe the variation.
