The girls write the names of the states (removing Maryland) on index cards and place the cards into a hat. Then, they randomly draw ten names of states and record the names of the states in the first column of a table. They find the average yearly snowfall for each of the selected states and record this information in the second column of their table.

Allyson enters the average snowfall amounts for the selected states into L1 on a graphing calculator. Allyson then determines the mean or average of the “Average Snowfall” amounts for the selected states by using the one-variable statistics capabilities of her graphing calculator. The results are shown below:

Marissa: Maryland’s average snow fall is 20.6 inches. Thus, Maryland, on average, is below the other states with respect to average amount of snowfall.
