Chapter 10 questions: 1. Problem 20 on page 460 of textbook. 20. A teller at a driveup window at a bank had the followaing service times (ie minutes) for 20 randomly selected customers. Pape 460 a. Determine the mean of each sample. b. If the process parameteri are unknown, estimate its mean and standard deviation, e. Estimate the mean and standard deviation of the sampling distribution. d. What would threesigma control limits for the process be? What alpha rick would they provide? e. What alpha risk would control limiss of 4.14 and 4.86 provide? f. Using timits of 4.14 and 4.\$6, are any sample means beyoad the control limits? If so, which one(s)? g. Construct control charts for means and ranges using [3] Table 10.3. Are any samples beyond the control limits? if eo, which one(s)? h. Explain why the control limits are different for means in parts d and g. 1. If the process has a known mean of 4.4 and a known standard deviation of . 18 , what would three-sigena control limats be for a mean chart? Are any sample neans beyond the controd limits? If so. which one(s)? 20. A teller at a drive-up window at a bank had the following service times (in minutes) for 20 randomly selected customers. Page 460 a. Determine the mean of each sample. b.
