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.

Complete parts (a) through (e), given Σx
= 372, Σy
= 116, Σx
²
= 24814, Σy
²
= 3320, Σxy
= 8512, and
r
≈ 0.961.

(b) Verify the given sums Σx, Σy, Σx
², Σy
², Σxy, and the value of the sample correlation coefficient
r. (Round your value for
r
to three decimal places.)

(c) Find x, and y. Then find the equation of the least-squares line =
a
+
bx. (Round your answers for x and y to two decimal places. Round your answers for
a
and
b
to three decimal places.)
