In 1990 the number of driver deaths per 100,000 for the different age groups was as follows (Source: The National Highway Traffic Safety Administration's National Center for Statistics and Analysis):

Age Number of Driver Deaths per 100,000

15-24 28

25-39 15

40-69 10

70-79 15

80+ 25

Using ages as the independent variable and Number of driver deaths per 100,000 as the

dependent variable, make a scatter plot of the data.

Find the correlation coefficient. Is it significant?

Use the two points in (e) to plot the least squares line on your graph from (b).
