Linear vs Nonlinear Association

Which relationship is shown by this scatter plot?

• As the cost goes down, the number sold goes

  down.

• As the cost goes up, the number sold goes

  down.

• As the cost does down, the number sold

  remains the same.

• There is no relationship between cost and the

  number sold.

The daily attendance at a bowling alley was recorded for 15 days. The scatterplot shows the number of lanes rented each day and the number of people who bowled that day. Which statement is best supported by the scatterplot?

• There is a non-linear assocation between the number of lanes rented and the number of people who bowl.

• There is a negative linear association between the number of lanes rented and the number of people who bowl.

• There is no apparent association between the number of lanes rented and the number of people who bowl.

• There is a positive linear association between the number of lanes rented and the number of people who bowl.
