A ski resort records the weekly number of skiers and inches of snow as shown in the table. Create a line of best fit to predict how many skiers they could expect if they get 6 inches of snow.

(Hint: Use the graphing calculator to help you write your line of best fit, the prediction equation)

• 12 skiers

• 115 skiers

• 220 skiers

• 100 skiers

• The overall shape will decrease from left to right.

• The scatter plot has a negative association.

• As the value of x increases, the value of y decreases.

• The scatter plot has strong association.

Which of the following correlation coefficients best represents the scatter plot shown?
