Answer #1

The Xbar chart is a variable control,chart used tom montor the process mean over time. The chart shows sample means over the time and uses the dispersion in the sample to construct the upper and lower specification limits of the mean.

All the statements are correct. The correct answer is E.

    Control charts for bar x chart and S have been maintained on a process and have exhibited statistical control. The sample size is n=6. The control chart parameters are as follows: Estimate the mean and standard deviation of the process. Assume that the process output is well modeled by a normal distribution. If specifications are 703 and 709, estimate the fraction nonconforming. Suppose the process mean shifts to 702.00 while the standard deviation remains constant. What is the probability of...

It is not necessary to sketch the control-chart since we have no points to put on it. Just specify, CL, UCL and LCL. That is the design. Then find the probability of in-control nonconformance given, USL = 4.00995 and LSL = 3.99005 Also, by theory, what is the Probability of an out-of-control point...

    A control chart is used for monitoring a process meanl (X) that is normally distributed with a mean of μ and a standard deviation of σχ , and the sample size is n-5. А 3-sigma limit (μ ±30% ) 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 out of...
