Probability of acceptance for defective percentage

Reference no: EM13981878

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. (The number 3 is known as the acceptance number of the sampling plan.)

a. Assuming that the shipment includes 3% defectives, what is the pro- bability that the shipment will be accepted? (Hint: Use the binomial distribution.)

b. Assuming that the shipment includes 6% defectives, what is the probabil- ity 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 ). (This graph is known as the operating characteristic curve of the sampling plan.)
