Auto Accidents: Age Let x be the age of a licensed driver in years. Let y be the percentage of all fatal accidents (for a given age) due to failure to yield the right-of-way. For example, the first data pair states that 5% of all fatal accidents of 37-year-olds are due to failure to yield the right-of-way. The Wall Street Journal article referenced in Problem 17 reported the following data:

x 37 47 57 67 77 87 y 5 8 10 16 30 43 Complete parts

(a) through (e), given Sx 5 372, Sy 5112, Sx2 5 24,814, Sy2 5 3194, Sxy 5 8254, and r < 0.943.

(f) Predict the percentage of all fatal accidents due to failing to yield the right-of-way for 70-year-olds.
