Determine the Average Run Length (ARL) of a x-bar chart with limits at 2 sigma where the process is incontrol and the rule to stop the process is to have at least 2 out of 3 points beyond the same side of the two-sigma limits, on either side (Western Electric Rule #2) PLEASE SHOW WORK

What is the relationship between Average Run Length (ARL) and Type I (a – alpha) and Type II (b– Beta) errors relative to the control chart. What practical implication in terms of process operation do these two types of errors have? on excel The length in minutes of calls made to a call center is measured. A normal distribution with a mean value of 46.8 minutes and a standard deviation of 1.75 minutes is postulated. Consider randomly selecting a single...

2. A process has a X-bar control chart with UCL=17.4, LCL=12.79 using a 3- sigma limit. The subgroup sample size is 3. (a) Estimate the standard deviation of the process, sigma hat. (6 pts) (b) Suppose that the process mean shifts to 13. Find the probability that this shift will be detected on the next sample. (8 pts) (c) Calculate the average run length (ARL) before detecting the shift. (6 pts)

A control chart is to be established on a process producing refrigerators. The inspection unit is one refrigerator, and a common chart for nonconformities is to be used. As preliminary data, 16 nonconformities were counted in inspecting 30 refrigerators. (a) What are the three-sigma control limits? (b) What is the α-risk for this control chart? (c) What is the β-risk if the average number of defects is actually 2 (i.e., if c = 2.0)? (d) Find the average run length...

A 3-sigma control chart is established and the following two rules are used together to detect process outof-control situations. Rule 1: A point is plotted outside of the control limits. Rule 2: A run of eight consecutive points on one side of the center line but still inside the control limits. Compute the following: (a) Type I error of Rule 1 (b) Type I error of Rule 2 (c) Type 1 error of using both rules together

17. Management at Webster, in Problem 16, is now concerned as to whether caulking tubes are being properly capped. If a significant proportion of the tubes are not being sealed, Webster is placing its customers in a messy situation. Tubes are packaged in large boxes of 144. Several boxes are inspected, and the following numbers of leaking tubes are found: Sample Tubes...

A control chart is used for monitoring a process mean ( 7 ) that is normally distributed with a mean of u and a standard deviation of o, and the sample size is n = 5. A 3-sigma limit (u +30z) is used as control limits. Two decision rules are given here. Rule 1: If one or more of the next seven samples yield values of the sample average that fall outside the control limits, conclude that the process is...
