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.)
Question 1: A company making tires for bikes is concerned about the exact width of its cyclocross tires. The company has a lower specification limit of 22.8 mm and an upper specification limit of 23.2 mm. The standard deviation is 0.15 mm and the mean is 23 mm. What is the process capability index (Cpk) for the process? Question 2: Consider again that the company making tires for bikes is concerned about the exact width of its cyclocross tires. The company has a lower specification limit of 22.8 mm and an upper specification limit of 23.2 mm. The standard deviation is 0.15 mm and the mean is 23 mm. What is the probability that a tire will either be too wide or too narrow?

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.
