T T [V D. e results 0 (a) and (c) are the same: there is not sufficient evidence to prove that the mean life is different from 7.529 hours The quality-control manager at a compact fluorescent light bulb (CFL) factory needs to determine whether the mean life of a large shipment of CFLs is equal to 7,529 hours. The population standard deviation is 92 hours. A random sample of 64 light bulbs indicates a sample mean life of 7,506 hours. a. At the 0.05 level of significance, is there evidence that the mean life is different from 7,529 hours? b. Compute the p-value and interpret its meaning. c. Construct a 95% confidence interval estimate of the population mean life of the light bulbs. d. Compare the results of (a) and (c). What conclusions do you reach? a. Let u be the population mean. Determine the null hypothesis, Ho, and the alternative hypothesis, H. Ho : H = Hy: up What is the test statistic? ZSTAT = (Round to two decimal places as needed.) What is/are the critical value(s)? (Round to two decimal places as needed. Use a comma to separate answers as needed.) What is the final conclusion? A. Reject Ho. There is not sufficient evidence to prove that the mean life is different from 7,529 hours. O B. Reject Ho. There is sufficient evidence to prove that the mean life is different from 7,529 hours. O C. Fail to reject Ho. There is not sufficient evidence to prove that the mean life is different from 7,529 hours. O D. Fail to reject Ho. There is sufficient evidence to prove that the mean life is different from 7,529 hours
