The box plots show the data distributions for the number of laps two students run around a track each day.

The difference between the medians of both data sets is 2.

The difference between the medians of both data sets is 4.

The difference between the ranges of both data sets is 2.

The box plots represent the ages of pennies in two 50-cent rolls.

She is correct because the medians are 10 years apart, which means the means are half of that, or 5 years apart.

She is correct because the maximum ages of the pennies in each set are 5 years apart.

She is not correct because the means are both equal to 12.

She may not be correct because means cannot be determined from the box plots.

The histogram represents the distributions of boiling temperatures, in degrees Celsius, of tap water and a mixture of salt water.

The two distributions are each nearly symmetric.

The distributions do not overlap on the same range of temperatures.

The distribution of salt water boiling temperatures is left-skewed.

The distribution of tap water boiling temperatures is right-skewed.

The histogram shows the distributions of essay scores for high school sophomores and juniors in a contest. Which comparison of the distributions is true?

The distribution of sophomores’ scores is right-skewed, and the distribution of juniors’ scores is left-skewed.

The distribution of sophomores’ scores is left-skewed, and the distribution of juniors’ scores is right-skewed.

The histogram shows the prices for six-packs of adult socks and six-packs of kid socks at a store. What is true about the variability of the prices of socks in kid sizes or adult sizes?

There is more variability in the prices of kid socks because they have a greater range.

There is more variability in the prices of kid socks because the median is lower.

There is more variability in the prices of adult socks because there are two bars of equal height.

There is more variability in the prices of adult socks because the median is greater.
