Block Enterprises, a manufacturer of chips for computers, is in the process of deciding whether to replace its current semi-automated assembly line with a fully automated assembly line. Block has gathered some preliminary test data about hourly chip production, which is summarized in the following table: Production Technique Sample Mean Semi-automated Fully-automated 172 199 Sample Standard Deviation Sample Size (n) 32 29 15 10 A. Determine whether there is likely a difference in the population mean between semi-automated and fully-automated production. Use a=0.10. Comment on your results. B. Determine whether there is likely a difference in the population variance between semi-automated and fully-automated production. Use a = 0.05. Comment on your results.
