To decision rules are given here. Assume they apply to a normally distributed quality characteristic, the control chart has three-sigma control limits, and the sample size n = 5. Rule 1: If one or moreof the next seven samples yield values of the sample average that fall outside the control limits, conclude that the process is out of control.
Rule 2: If all of the next seven sample averages fall on the same side of the center line, conclude that the process is out of control.
a) What is the Type-I error probability for each of these rules?
b) If the mean of the quality characteristic shifts one process standard deviation, and remains there during the collection of the next seven samples, what is the Type-II errorprobability associated with each decision rule?

Which of the following is equal to the rational expression when x is not equal to -2 or -6?

Lm is the midsegment of trapezoid abcd. if ab=46 and dc=125, what is lm?

The accompanying normal probability plot was constructed from a sample of 30 readings on tension for mesh screens behind the surface of video display tubes used in computer monitors. does it appear plausible that the tension distribution is normal? the given probability is has a significant downward curve, so it is plausible that the tension distribution is normal. the given probability is has a significant downward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is plausible that the tension distribution is normal. the given probability is has a significant upward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is not plausible that the tension distribution is normal.
