Help/FAQ @ Kristin Segovia CHALLENGE 6.2.2: Relating confidence intervals to hypothesis testing (one sample). Your question: Subject: Statistics and Probability Course: MAT 240 Jump to level 1 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 What is the level of significance? Ex: 0.12 9 Observations hypothesized Mean What is the null hypothesis Ho? Pick Answer from your tutor: Report this answer t Stat P(T <=t) one-tail What is the alternative hypothesis Ha? Pick t Critical one-tail P(T<=t) two-tail Should Ho be rejected or does Ho fail to be rejected? Pick Merbone Answered 30 minutes ago critical two-tail Confidence Level(95.0%) 0.641 What conclusion can be drawn from the data? P=0.017 t= 2.185 Pick the sample size is larger than 30 What is the 95% confidence interval for the mean life of a transmission? [ Ex: 1.234], 1 = 46 Z = 150.7 Does the confidence interval support the results of the hypothesis test? Pick v degrees of freedom = 45 Why ?

Disregard right screen shot.WHat is the null hypothesis - (Pick) u < 150,000 or = 150,000 or > 150,000What is the alternative hypothesis Ha? (Pick) same chooses as aboveShould H0 be rejected or does H0 fail to be rejected? (Pick) Fail to reject or rejectWhat conclusion can be drawn from the data? (Pick ) Convincing Evidence does not exist to conclude the mean life of a transmission is over 150,000 or there evidence the mean life of transmission is over 150,000 What is the 95% confidence interval for the mean life of a transmission? Does the confidence interval support the results of the hypothesis test? (Pick) yes or noWhy? (Pick) The hypothesized mean falls outside the bounds of the confidence interval orThe hypothesized mean falls within the bounds of confidence interval Math Statistics and Probability MAT 240 Share QuestionEmailCopy link Comments (0)
