Draw a scatter plot that shows a negative, linear association and has one clear outlier. Circle the outlier. Have at least 5 total points. 

The fitted line has a slope of 5. What is the best interpretation of this slope?

• We would predict that the diameter of 0 would have a volume of 5.

• We would predict that the diameter of 5 would have a volume of 0. 

• We would predict that the diameter of 1 would have a volume of 5. 

• We would predict that the diameter of 5 would have a volume of 1.

Using the trend line, when the temperature is 21 degrees, what would the sales amount be?

• $480

• $425

• $500

• $450

Circle any data points that appear to be outliers

Answer explanation

Circle the point at (2.1, 18.6)

What does it mean for a point to be far above the line in this situation?

Answer explanation

A point above the line represents a player who scores more points per game than predicted by their number of free throw attempts.

Based on the model, how many points per game would you expect a player who attempts 4.5 free throws per game to have? Round your answer to the nearest tenth of a point per game.

Answer explanation

20.2 points per game, because 4.413(4.5) + 0.377 is roughly equal to 20.2.

One of the players scored 13.7 points per game with 4.1 free throw attempts per game. How does this compare to what the model predicts for this player?

Answer explanation

The model predicts that with 4.1 free throw attempts per game, the player should score 4.413(4.1) + 0.377, or about 18.5 points per game. That means the player is scoring less than the model predicts they should.
