2. (12 points) in lecture, examples were shown on how to calculate the points of operating curves assuming the lot size, N, is finite. For this exercise, assume N is infinite. Suppose now that a quality engineer samples 50 units from an infinite lot size and the engineer would like to calculate a point of the operating characteristic curve for an acceptance number 2 . Calculate the point at which the lot proportion of defectives, p, equals 0.06 ..
