Q:

A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 36 ​tablets, then accept the whole batch if there is only one or none that​ doesn't meet the required specifications. If one shipment of 5000 aspirin tablets actually has a 2​% rate of​ defects, what is the probability that this whole shipment will be​ accepted? Will almost all such shipments be​ accepted, or will many be​ rejected?

Accepted Solution

A:
Answer:The probability that this whole shipment will be​ accepted is 0.8382. Almost all such shipments be​ accepted as the probability of accepting is higher. Step-by-step explanation:Consider the provided information.The probability for accepting the whole batch if there is only one or none that​ doesn't meet the required specifications.Aspirin tablets actually has a 2​% rate of​ defects. Thus, the rate of aspirin tablets are not defected 98%.Which can be written as:P(x=0 or x=1)P(no defects out of 36)=[tex]^{36}c_0 \times (0.02)^0 \times (0.98)^{36}[/tex]P(no defects out of 36)=[tex]0.483213128206[/tex]P(one defects out of 36)=[tex]^{36}c_1 \times (0.02)^1 \times (0.98)^{35}[/tex]P(one defects out of 36)=[tex]36 \times 0.02 \times (0.49307)[/tex]P(one defects out of 36)=[tex]0.3550104[/tex]The probability that the whole shipment will accepted is the sum of the individual probabilities which is:0.4832+0.3550=0.8382Hence, the probability that this whole shipment will be​ accepted is 0.8382. Almost all such shipments be​ accepted as the probability of accepting is higher.
