Consider a product organized into inspection lots of N=1800 items and for which u1=75 gm. For this product, u2u=78 gm, u2l=72 gm, and s=2 gm. Construct a variables acceptance sampling plan with respect to the mean for the case in which b=0.06 and alpha is approximately 0.05. For the plan you obtain, compute the adjusted value of the producer's risk parameter. Compute the probability of acceptance for lots from a population having u=74.2 gm.
