Question 5: What conclusion can be drawn from the data?

Question 6: What is the 95% confidence interval for the mean life of a transmission?

Question 7: Does the confidence interval support the results of the hypothesis test?

A 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. Milt: (mm: 9! miles!
