With practice, people become faster at solving a certain type of mathematical puzzle. Fourteen college students were allowed to practice completing a certain type of mathematical puzzle for different amounts of time. Afterwards, each student’s completion time on a new puzzle was measured. The Residual plot for regression of Completion Time on Practice Time is shown below. Which of the following is correct?

• There is a no relationship between Practice Time and Puzzle Completion Time.

• This regression equation would likely overestimate the Puzzle Completion Time for 175 minutes of practice time.

• There is a non-linear relationship between Practice Time and Puzzle Completion Time.

The hourly salaries of the workers at a restaurant are shown below.

$7.75, $8.50, $7.25, $9.00, $30.00, $8.25, $7.75, $9.00

Identify the outlier and use it to determine which statement is true.

• The outlier is $7.25 which causes the mean to be a better representation of the typical salary than the median.

• The outlier is $7.25 which causes the median to be a better representation of typical salary than the mean.

• The outlier is $30.00 which causes the mean to be a better representation of the typical salary than the median.

• The outlier is $30.00 which causes the median to be a better representation of the typical salary than the mean.
