The answer choice for the multiple choice questions are below:Am I right about the null and alternative hypothesis?What conclusion can be drawn from the data? (Convincing evidence does not exist to conclude that the mean life of a transmission is over 150,000 miles, or Convincing evidence exist to conclude that the mean life of a transmission Is over 150,000 miles)Does the confidence interval support the results of the hypothesis test? (Yes or no)Why? (The hypothesized mean falls outside the bounds of the confidence interval, or The hypothesized Mean falls within the bounds of the confidence interval)

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. 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? H = 150,000 t Stat 2.17 P(T 150,000C t Critical one-tail 1.683 P(T
