An x? chart is to be established based on the standard values ? = 600 and ? = 12, with n = 9. The control limits are to be based on an ?-risk of 0.01. What are the appropriate control limits?

Step 1
- The mean (μ) is given as 600. - The standard deviation (σ) is given as 12. - The sample size (n) is given as 9. - The α-risk (probability of a type I error) is given as 0.01. - We are asked to find the control limits for an X chart. Show more…

The control limits for an $\bar{X}$ chart with $n=4$ are 12.8 and 24.8 , and the $P C R$ for a measurement is 1.33 . (a) Estimate the process standard deviation $\sigma$ (b) Calculate the specification limits. Assume that they are centered around the process mean.

(a) Find the three-sigma control limits for a c chart with process average equal to nine nonconformities. (b) Find the three-sigma control limits for a u chart with c = 16 and n = 4. (c) Find 0.980 and 0.020 probability limits for a control chart for nonconformities per unit when u = 6.0 and n = 3. (d) The standard values of the process mean and variance are given as 50 and 4 respectively. Determine the sample size for the establishment of x bar chart to ensure that the process remains in control
