A shipment of thousands of pins contains some percentage of defectives. To decide whether to accept the shipment, the consumer follows a sampling plan where 80 items are chosen at random from the sample and tested. If the number of defectives in the sample is at most three, the shipment is accepted.

a. Assuming that the shipment includes 3% defectives, what is the probability that the shipment will be accepted?

b. Assuming that the shipment includes 6% defectives, what is the probability that the shipment will be accepted?

c. Using the Data Table command; tabulate the probability of acceptance for defective percentage ranging from 0% to 15% in steps of 1%.

d. Plot a line graph of the table created in (c).
