A manager is simulating the number of times a machine operator stops a machine to make adjustments. After careful study themanager found that the number of stops ranged from one to five per cycle and that each number of stops was equally likely. Using therandom numbers 0.77 and 0.62 (in that order), determine how many stops for adjustments each of the next two cycles will have.The first cycle will havestops and the second cycle will havestops.

3- Wellplace Insurance Company processes insurance policy applications in batches of 50. One day, they had 10 batches to process and, after inspection, it was found that four batches had nonconforming policies. One batch had 3 nonconformances, another had 5, another had 2, and another had 1 nonconformance. What were (a) the proportion nonconforming for each batch, (b) the nonconformances per unit (NPU), in total for the 10 batches, and (c) the total throughput yield (TY) for the 10 batches? 4- Boardwalk Electronics manufactures 300,000 circuit boards per month. A random sample of 3,000 boards is inspected every week for five characteristics. During a recent week, three defects were found for one characteristic, and two defects each were found for the other four characteristics. If these inspections produced defect counts that were representative of the population, what are the dpmo’s for the individual characteristics and what is the overall dpmo for the boards?
A manager is simulating the number of times a machine operator stops a machine to make adjustments. After careful study the manager found that the number of stops ranged from one to five per cycle and that each number of stops was equally likely. Using the random numbers 0.17 and 0.47 (in that order), determine how many stops for adjustments each of the next two cycles will have. The first cycle will have stops and the second cycle will have stops.

Ashley’s department store in Kansas City maintains a successful catalog sales department in which four clerk takes orders by telephone. If four clerks are occupied on four-lines, incoming phone calls to the catalog department are answered automatically by a recording machine and asked to wait. As soon as the clerk is free, the party that has waited for the longest is transferred and answered first. Calls come in an average of 3 minutes. The clerk is capable of taking an order in an average of 10 minutes. Calls tend to follow a Poisson distribution, and service times tend to be exponential. a. λ= μ= b. Calculate P0 c. How many callers, on average, are waiting to place an order under the current operating system?
Problem 13-4 (Algo) There is a 3 percent error rate at a specific point in a production process. If an inspector is placed at this point, all the defects can be detected and eliminated. The inspector would cost $11 per hour and could inspect units in the process at the current production rate of 52 per hour. If no inspector is hired and defects are allowed to pass this point, there is a cost of $12 per defective unit to correct the defects later on. Assume that the line will operate at the same rate (i.e., the current production rate) regardless of whether the inspector is hired or not. a. If an inspector is hired, what will be the inspection cost per unit? (Round your answer to 3 decimal places.) Cost per unit b. If an inspector is not hired, what will be the defective cost per unit? (Round your answer to 3 decimal places.) Cost per unit
The mean service time (x¯) of a hairdresser is 18 minutes with a standard deviation (σ) of 2 minutes.

Is the process capable? Cpk=0.67, capable Cpk=1.5, capable Cpk=0.67, not capable Cpk=0.5, capable Cpk=0.5, not capable
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 3.0 minutes; Jerry, a mean of 34.0 minutes and a standard deviation of 2.0 minutes; and Melissa, a mean of 37.5 minutes and a standard deviation of 1.7 minutes. a.Compute process capability for the participants and determine whether each is capable.
