Overall average, X̅̅ = 705 cc
Average range, R̅ = 6 cc
Corresponding to sample size, n = 10, the control chart constants are:
A2 = 0.308
D3 = 0.223
D4 = 1.777
Upper Control Limit:
Mean: UCLX̅ = X̅̅ + A2*R̅ = 705 + 0.308*6 = 706.85
Range: UCLR = D4*R̅ = 1.777*6 = 10.66
Lower Control Limit:
Mean: LCLX̅ = X̅̅ - A2*R̅ = 705 - 0.308*6 = 703.15
Range: LCLR = D3*R̅ = 0.223*6 = 1.34

Suppose production specifications for a new energy drink require exactly 40 mg of vitamins per serving. Fred, a quality control engineer, suspects that the production process does not ensure each serving contains 40 mg of vitamins, on average To test his suspicions, Fred collects a random sample of 8 servings and determines their average vitamin content to be 34.9985 mg with a standard deviation of 6.9871 mg. Fred uses a 95% confidence interval to test the null hypothesis Ho: μ-μο...
