A quаlity cоntrоl inspectiоn system requires thаt from eаch batch of Covid-19 tests a sample of 30 is selected and tested for accuracy. If 3 or more of the sample are defective (report the wrong conclusion about positivity) the whole batch is rejected. Assume that the probability that any one test is defective is 6%. Show all work for full credit. a. Explain why X=the number of defects is a Binomial Random Variable. (4 conditions needed) b. Find the probability of exactly 3 defectives in the sample. c. Find the probability of finding less than 3 defects. d. Find the probability of the batch being rejected.
