As part of an insurance company’s training program, participants learn how to conduct an analysis of clients’ insurability. The goal is to have participants achieve a time in the range of 30 to 45 minutes. Test results for three participants were the following: Armand, a mean of 36.0 minutes and a standard deviation of 2.0 minutes; Jerry, a mean of 37.0 minutes and a standard deviation of 2.0 minutes; and Melissa, a mean of 37.5 minutes and a standard deviation of 2.6 minutes. a.Compute process capability for the participants and determine whether each is capable, given 4-sigma quality standards. (Do not round intermediate calculations. Round your answers to 2 decimal places.)

The Money Pit Mortgage Company is interested in monitoring the performance of the mortgage process. Fifteen samples of five completed mortgage transactions each 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 of the mortgage process transaction times, measured in days, are as follows: Sample Mean Range ew an example 1 2 16 12 7 12 Get more help. 3 6 5 4 5 6 7 8 9 15 10 10 13 14 11 9 10 16 13 16 11 Subsequently, samples of size 5 were taken from the process every week for the next 10 weeks. The times were measured and the following results obtained: D Sample Mean Range 16 9 8 17 12 12 18 19 13 7 7 5 20 15 13 MacBook Pro Click the icon to view the table of factors for calculating three-sigma limits for the x-chart and R-chart. a. Construct the control charts for the mean and the range, using the original 15 samples. Set up the R-chart by specifying the center line and three-sigma control…

Why are Taguchi experiments so important compared to classical DOE-type experiments?  

Prepare a run diagram for this emergency call data. Use five-minute intervals (i.e., count the calls received in each five- minute interval. Use intervals of 0-4, 5-9, etc.). Note: Two or more calls may occur in the same minute; there were three operators on duty this night. What can you conclude from the run chart? Call Time Call Time Call Time 1 2 3 4 5 6 7 8 9 10 11 1:03 1:06 1:09 1:11 1:12 1:17 1:21 1:27 1:28 1:29 1:31 12 13 14 15 16 17 18 19 20 21 22 1:36 1:39 1:42 1:43 1:44 1:47 1:48 1:50 1:52 1:53 1:56 23 24 25 26 27 28 29 30 31 32 33 1:56 2:00 2:00 2:01 2:02 2:03 2:03 2:04 2:06 2:07 2:08 Call 34 35 36 37 38 39 40 41 42 Time 2:08 2:11 2:12 2:12 2:13 2:14 2:14 2:16 2:19 a. re-organize the above data for your analysis (using five-minute intervals; 0-4, 5-9, etc) b. Provide your diagram that shows the number of emergency calls by eacn five-minute intervals from 1am to 2:20am c. what can you conclude from the chart?
