Approach Analysis
We’re dealing with a p-chart style calculation for a defect rate, using the historical proportion p0 = 0.02 and a sample size n = 100 with 3-sigma limits.
First, compute the standard error term: sqrt[p0(1 - p0) / n] = sqrt[0.02 * 0.98 / 100] = sqrt[0.0196 / 100] = sqrt[0.000196] ≈ 0.0140.
Then, multiply by 3 to obt......Login to view full explanationLog in for full answers
