3. Auto Accidents: Age Let z 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: 37 47 57 67 77 87 y 5 8 10 16 30 43 Complete parts (a), (b), (c), (d), and (e), given Ex = 372, Ey = 112, Σr² = 24,814, Ey² 3194, Exy=8254, and -0.943. f. Predict the percentage of all fatal accidents due to failing to yield the right-of- way for 70-year-olds.
