question

A Maine weatherman tracked the amount of snowfall during each of their past few storms.

Snowfall in Maine

number line label

Inches of snow

Select all the statements that describe the distribution of the data.

The distribution is roughly symmetric.

The data has a peak at 10 inches of snow.

There is a cluster from 10 to 14 inches of snow.

solution

Look at the line plot.

Snowfall in Maine

number line label

Inches of snow

See if each statement describes the distribution of the data.

green checkmark, The distribution is roughly symmetric.

The left and right sides of the distribution are almost mirror images. So, the distribution is roughly symmetric.

red X symbol, The data has a peak at 10 inches of snow.

The column for 12 has the most Xs. So there is a peak at 12 inches of snow, not at 10.

green checkmark, There is a cluster from 10 to 14 inches of snow.

There is a group of Xs in the columns for 10, 12, and 14. Every column has at least one X, and the columns are next to one another. So, there is a cluster from 10 to 14 inches of snow.
