The scatterplot below shows the amount of sales in dollars as it relates to the daily temperature. Which of the following best describes the relationship between the two variables?

• The scatterplot has a linear shape and displays a strong positive relationship. This means that as the temperature increases the sales increase.

• The scatterplot has a curved shape and displays a weak positive relationship. This means that as the temperature increases the sales increase.

• The scatterplot has a linear shape and displays a strong negative relationship. This means that as the temperature increases the sales decrease.

• The scatterplot has no noticeable shape and displays a weak positive relationship. This means that as the temperature increases the sales increase.

• -2

• 1

• 10

An organization examined the cell phone records and recorded the number of text messages sent on a particular day for 400 randomly selected males and 400 randomly selected females between the ages of 14 and 17. The dotplots below show distributions of the number of text messages sent that day. Which of the following is a valid statement?

• The standard deviation is about the same for both distributions because they both have about the same range.

• The standard deviation is greater for the females' distribution because the frequencies go up and down more often than in the males' distribution.

• The standard deviation is greater for the females' distribution because the values are not clustered as tightly as for the males' distribution.

• The standard deviation is greater for the males' distribution because of the outlier around 230 text messages per day.
