please answer within 30 minutes. The Money Pit Mortgage Company is interested in monitoring the performance of the mortgage process. Fifteen samples of five completed mortgage transactionseach were taken during a period when the process was believed to be in control. The times to complete the transactions were measured. The means and ranges ofthe mortgage process transaction times, measured in days, are as follows:12 13 14 15Sample 1 2 3 4Mean 19 16 10 196 10 3 75 6 7 8 9 10 1114 14 17 18 15 16 178 12 11 14 910 511 1311 14Range98 10 12Subsequently, samples of size 5 were taken from the process every week for the next 10 weeks.

Answer C only. Tim Woods, a recent GMU MBA grad and serial entrepreneur, has opened Pets-R-awesOMe, an online pet store. He and his team are experimenting with call center staffing. A. The current call center format has two lines: one for customers who want to place an order and one for customers who want to report a problem. Each line is served by one specialized customer service representative. The call center is staffed so that at any given time, there is one representative taking customer orders and one representative addressing customer problems. On average, there is a new customer who wants to place an order every two minutes, exponentially distributed. Similarly, there is a new customer needing to address a problem every two minutes, exponentially distributed. The call center staffers are fast and can on average complete one call of either type in 75 seconds, with a standard deviation of 30 seconds. Each call center staff member is paid $15 per hour. The estimated cost of a…

Employee Wanda Trews was working in the manufacturing facility at Coves Industrial. The employees of Coves Industrial manufacture diesel engines for the airline industry. Wanda works on Line 3 in the facility and from time-to-time works on Line 7 as a relief worker to cover employee breaks.

When Wanda arrived at Line 7 to provide break coverage, she checks in with Line 7 supervisor Raoul Steves. Raoul advises that Wanda needs to manufacture 200 components during her 2 hours on Line 7 and to let him know if she needs any help. Raoul does not mention the earlier mechanical issue with…
