Which of the following books best represents an outlier?

• Book 7

• Book 3

• Book 8

• There were no outliers in the scatter plot

Give the ordered pair for the outlier in the given scatterplot.

The scatterplot shows the results of study comparing the length of a person's foot to the width.

How can you describe the correlation of the within the context of the situation?

• There is no correlation.

• As the length of a person's foot increases, the width increases.

• As the length of the person's foot increases, the width decreases.

• The tall a person is, the bigger their shoe size will be.

The scatterplot shows how many hours per week the debate team practices compared with the amount of debates won. Determine if the statement is True or False, if false correct the statement: There is a nonlinear negative association between the hours practiced and the number of wins.

• False. There is a nonlinear positive association between the hours practiced and the number of

• False. There is a linear positive association between the hours practiced and the number of wins.

• There is no association between the hours practiced and the number of wins.

• True.

Write the equation for the trend line

How can you determine if the association on a scatter plot is strong or weak?

• By observing how large the y-intercept is.

• By observing how large the slope of the trend line is.

• By observing how closely the points of the scatter plot are located to one another.

• By observing whether or not the scatter plot is linear.
