Question

A research engineer for a tire manufacturer is investigating tire life for a new rubber compound and has built 16 tires and tested them to end-of-life in a road test. The sample mean and standard deviation are 60,139.7 and 3211.65 kilometers.
You want to test that the standard deviation of tire life is less than 4000 kilometers?
State bounds for the P-value of this test.

a.)0.001 < P-value < 0.005

b.)0.7 < P-value < 0.9

c.)0.1 < P-value < 0.5

d.)0.01 < P-value < 0.05
