DETAILS MY NOTES ASK YOUR T You may need to use the appropriate appendix table or technology to answer this question. Maxforce, Inc., manufactures racquetball racquets by two different manufacturing processes (A and B). Because the management of this company is Interested in estimating the difference between the average time It takes each process to produce a racquet, they selected independent samples from each process. The results of the samples and the population variances are shown below. Process A Process B Sample Size Sample Mean (in minutes) Population Variance (62) (a) Develop a 95% confidence interval estimate for the difference between the average time taken by the two processes. (Use Process A - Process B. Round your answers to three decimal places.) to (b) Is there conclusive evidence to prove that one process takes longer than the other? If yes, which process? Explain. Because the range of the interval is from negative to negative, it indicates that there is conclusive evidence (at 95% confidence) that Process A takes longer. Because the range of the interval is from negative to positive, it indicates that there is conclusive evidence (at 95% confidence) that Process B takes longer. Because the range of the interval is from negative to positive, It indicates that there is conclusive evidence (at 95% confidence) that Process A takes longer. Because the range of the Interval is from negative to negative, It Indicates that there is conclusive evidence (at 95% confidence) that Process B takes longer.
