Homework Answers
TRUE - Because the mean chart is taken as the actual chart but an individual sample may be not matched with that because mean is not match with each individual
FALSE - at zero LCL is zero not negative or positive

In order to establish a control chart for the mean of a process,
20 samples each of size 4
are collected. We note that
P20
i=1 xi = 4000 and
P20
i=1 si = 500. The value of the lower
control limit of the chart for the mean is approximately equal to
195.5.

1. Design X-bar and R charts a control chart with "standards given" as an aimed-at mean of Xo = 4.0, Sigma = .0033, and Subgroup size -5. 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. 2. Then find the probability of in-control nonconformance given, USL = 4.00995 and LSL 3.99005 3. Also, by theory, what is the Probability of an out-of-control...
