The objective of Scenario 3 is to assess your ability Scenario 3: A company that manufactures treadmills has one supplier for its electric motors. The company took a random sample from its current supplier and to generate and conduct a one-sample hypothesis ran the motors until they failed to see how long they might last. The current supplier test for the population mean using Excel. See claims their motor has an average hours-to-failure of 765 hours. Based on the Section 4, Chapter 9. Show your answers to random sample from the supplier's production, the treadmill company suspects the three decimal places (for example, 52.414). average time-to-faliure is less than 765 hours? Use the t distribution to set up and conduct a hypothesis test and answer the questions that follow. Current 1358 793 587 608 472 Answers 562 879 575 10 What is the value of the test statistic for this hypothesis test? Show your answer to three 1293 decimal places. 705 623 11 What is the the p-value for a one-tailed test? Show your answer to three decimal places. 725 See Section 9.4 "Using Excel." 569 424 12 With an alpha of 0.05 and a one-tailed test, should we reject the null hypothesis that the 462 average hours-to-failure for the suppliers is equal? Yes or No. 765
