A new design for the braking
system of a car has been proposed. For the current system, the true
average braking distance at 40 mph is known to be 120ft. It is
proposed that the new design be implemented only if sample data
strongly indicates a reduction in true average braking distance for
the new design.
Homework Answers
a)
values less than 120
b)
p-value = 0.036
As p-value < 0.1, reject H0
There are singnificant evidence to conclude that the mean is less
than 120
