Help/FAQ Lauren Kicklighter Jump to level 1 V 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 150.7 Variance 4.551 What is the level of significance? Ex: 0.12 # Observations 42 Hypothesized Mean 150 df 41 What is the null hypothesis Ho?
