8. You’re a quality control engineer at a computer chip manufacturer. You ship chips in lots of size 1000. Your sampling plan specifies that 50 chips be randomly sampled from each lot, and the lot is accepted if the number of defective chips is four or fewer. a. Find the probability of accepting a lot as a function of the actual fraction of defective chips. Use Excel to allow the fraction of defective chips to vary between 0.01 and 0.20, and compute the probability of lot acceptance for each of these fraction defectives. b. Plot the probability of lot acceptance versus the fraction defectives and comment.
