Production. Consider again the task of the quality control inspectors in Exercise 22. a) In this context, what is meant by the power of the test the inspectors conduct? b) They are currently testing 5 items each hour. Someone has proposed that they test 10 instead. What are the advantages and disadvantages of such a change? c) Their test currently uses a 5% level of significance. What are the advantages and disadvantages of changing to an alpha level of 1%? d) Suppose that, as a day passes, one of the machines on the assembly line produces more and more items that are defective. How will this affect the power of the test? Exercise 22 Quality control. Production managers on an assembly line must monitor the output to be sure that the level of defective products remains small. They periodically inspect a random sample of the items produced. If they find a significant increase in the proportion of items that must be rejected, they will halt the assembly process until the…

Burger Doodle is a fast-food restaurant that processes anaverage of 680 food orders each day. The average cost of each order is $6.15. Four percent of the orders are incor-rect, and only 10% of the defective orders can be corrected with additional food items at an average cost of $1.75. Theremaining defective orders have to be thrown out.a. Compute the average product cost.b. In order to reduce the number of wrong orders,Burger Doodle is going to invest in a computerizedordering and cash register system. The cost of thesystem will increase the average order cost by $0.05and will reduce defective orders to 1%. What is theannual net cost effect of this quality-improvementinitiative?c. What other indirect effects on quality might be realizedby the new computerized order system?
A process is in statistical control with = 202,5 y s = 2,0. Specifications are atLSL = 196 and USL = 206.a) Estimate the process capability with an appropriate process capability ratio.b) What is the potential capability of this process?c) Items that are produced below the lower specification limit must bescrapped, while items that are above the upper specification limit can bereworked. What proportion of the process output is scrap and whatproportion is rework?d) Because scrap is more expensive than rework, the process has been centered closer to the upper specification limit. If scrap is twice as expensive as rework, is the process mean at the best possible location? What value of the process target would you recommend?
You pull 5 bags of chips off of the production line every hour. The process is currently under control. The average weights are calculated for each sample, and the average of those averages is 129.1. The ranges are calculated for each sample, and the average of those ranges is 4.1. What is the Upper Control Limit for the X-bar chart? Round your answer to one decimal place.
This exercise contains only parts a and b. a) For the given data, the x= ____ hours (round your response to three decimal places).

Suppose that a processoutput is normally distributed with a mean of 30.0 and a variance of 1.44. If the specifications are 30.0 /- 3.25, then compute process capability indices. Is the process capable of meeting specifications?
1. The crossover point between two processes A and B can be stated as - [ ] a. variable costs of process A = Variable costs of process B - [ ] B. Fixed costs of process A = Fixed costs of process B - [ ] Variable costs of process A = Fixed costs of process B - [ ] total costs of process A = total costs of Process B
Pete works for Home Depot at the paint counter. Customers often ask to match a color already in their home—a fabric, a rug, or an older paint. He has a talent for this and can do it quickly if the base colors are standardized. His first step is a visual check of his base colors—a white, a blue, a red, and a yellow. Identify what kind of steps is this and explain why?
