The following data represents x = driver's age and y = average number of auto accident fatalities per

100,000 miles driven.

x = age y= fatality rate

18 38

22 36

30 24

44 20

64 18

1)Calculate the slope and intercept.

2)Write the equation of the best fit line.

3)Predict the most likely value of y for x = 36.

4)Would it be appropriate to predict y for x = 80?

5)What is the correlation coefficient?

6)What is r2?

7)Based on your answer to problem 6, what proportion of the variability in y (fatality rate) is

due to the relationship between x and y?
