Question 4 The Crunchy Potato Chip Company packages potato chips in a process designed for 12 ounces of chips with upper & lower specification limits of 124 0.14 ounces. The packaging process results in bags with an average weight of 12.07 ounces and a standard deviation of 0.28 ounces. What is the Cp value for this process? Specify a value using three decimals: e.g. X.XXX

Question Viewer 's, Inc., makes custom western shirts. The shirts could be flawed in various ways, including flaws in the weave or color of the fabric, loose buttons or decorations, wrong dimensions, and uneven stitches. Jim randomly examined 10 shirts, with the following results shown to the right. Shirt Defects 1 7 23 0 6 13 11 512608 45678 10 9 10 a. Assuming that 10 observations are adequate for these purposes, determine the three-sigma control limits for defects per shirt. The UCL equals and the LCL equals (Enter your responses rounded to two decimal places. If your answer for LCL is negative, enter this value as 0.)

QUESTION-2 In a process capability analysis, the specification limits are 65 + 3 mm and C, = 1 and 2 Cpk = Cpl = a) Draw the location of the normal distribution with respect to the specification limits. b) What is the nonconforming percentage of this system?

Problem 10-21 (Algo) A process that produces computer chips has a mean of .04 defective chips and a standard deviation of .003 chips. The allowable variation is from .032 to .048 defective. a.Compute the capability Index (C) for the process. (Round your Intermediate calculations to 3 decimal places and final answer to 2 decimal places.) Capability index b. Is the process capable? Hint. Use 1.33 as the standard capabality Index. O Yes O No

"The table below is data on telephone usage time by operators to serve customer requests that will be used to explain the use of Xbar and R-chart".   Question: a.    Create UCL and LCL with Limit Control Factor A2b.    Create UCL and LCL with Limit Control Factor D3 and D4

3.6. One of the stages in the process of making denim cloth at the Southern Mills Company is to spin cotton yarn onto spindles for subse- quent use in the weaving process. Occasionally the yarn breaks during the spinning process, and an operator ties it back together. Some num- ber of breaks is considered normal; however, too many breaks might mean that the yarn is of poor quality. In order to monitor this process, the quality-control manager randomly selects a spinning machine each hour and checks the number of breaks during a 15-minute period. Following is a summary of the observations for the past 20 hours: Number of Number of Sample Breaks Sample Breaks 1 3 11 3 2 12 4 3 4 13 4 1 14 7 5 15 8. 16 7 17 4 18 7. 8 19 8 9. 20 6. 10 Construct a c-chart using 3ơ limits for this process and indicate if the process was out of control at any time. ohoin when orders come into 3. 6
