Z = 3
SUM OF DEFECTS = 21
N = 14
C = SUM OF DEFECTS / N = 21 / 14 = 1.5
UCL = C + (Z * SQRT(C)) = 1.5 + (3 * SQRT(1.5)) = 5.174
LCL = C - (Z * SQRT(C)) = 1.5 - (3 * SQRT(1.5)) = -2.174 LCL <
0, THEREFORE LCL = 0

Determine the following:
a. The center line of the chart
b. Lower and upper control limits
c. Develop a p chart
2. Is the process in control? If the observations are within
control limits, does that guarantee that the process variation
contains only randomness?

4) Now that Continental can detect more defects before the Silver Box is shipped, I decided process Improvements in its circuit board fabrication department would further improve quality. So, for one process they collected the following data this morning to set up a mean control chart. Since the process mean is unknown, estimate the mean and find the UCL and LCL for a 3-sigma mean control chart using this morning's samples. Sample 1 - 24, 24, 25, 22, 21 Sample...
