An auto maker is interested in information about how long transmissions last. A sample of transmissions are run constantly and the number of miles before the transmission fails is recorded. The auto maker claims that the transmissions can run constantly for over 150,000 miles before failure. The results of the sample are given below. Miles (1000s of miles) Mean Variance Observations Hypothesized Mean df t Stat P(T<=t) one-tail t Critical one-tail 44 150 43 1.889 0.033 1.681 P(T<=t) two-tail 0.066 t Critical two-tail 2.017 Confidence Level(95.0%) 1.129 151.2 17.22 n = Ex: 5 Degrees of freedom = Ex: 5 -2 -1 0 x= Ex: 1.2 s Ex: 1.234 1 p= Ex: 1.234 3 t= Ex: 1.234 W 3
