Use Minitab How-To #29 and Table 11 in Appendix
B to solve the
following two exercises.
Exercise 1 Statement:
Braking Distances: Wet Surface. The
weights (in pounds) of eight vehicles and the variabilities of
their braking distances (in feet) when stopping on a wet surface
are shown in the table. Is there enough evidence to conclude
that there is a significant linear correlation between vehicle
weight and variability in braking distance on a wet surface.
Use alpha = 0.05.

Exercise 2 Statement: When x = 5700
pounds, find the predicted value of y.
