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) 150.7 Mean Variance 4.661 Observations 46 Hypothesized Mean 150 df 45 t Stat 2.185 p= Ex: 1.234 0.017 P(T<=t) one-tail t Critical one-tail P(T<nt) two-tail t Critical two-tail 1.679 0.034 Ex: 1.234 - 2.014 Confidence Level(95.0%) 0.641 What condition is met for the use of a t-distribution? The population is stated to be not skewed. -
