An Xത chart with three-sigma limits has parameters as follows: UCL = 104; Center Line = 100; LCL = 96; n = 5 Suppose the process
quality characteristic being controlled is normally distributed with a true mean of 98 and a standard deviation of 8. What is the probability that the control chart would exhibit lack of control by at least the third point plotted?
The perimeter is the measure around the shape, so just add all the sides together- 6+5x+x+2 6x+8 Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2 6(x+2) 6x+12 /2 3x+6
