I need all answers pls i will give 5 upvotes Question 4A process is in statistical control with x=205 and R = 15. The control chart uses a sample sizeof n = 6. Specifications are at 220 ± 10. The quality characteristic is normally distributed.1- Estimate the potential capability of the process Cp.2- Estimate the actual process capability.3- Calculate P the percentage of the specification band used up by the process4- Find a 95% confidence interval on Cp.

To find the margin of error for the 95% confidence interval, we multiply the standard error by the…

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
