Question

A pharmaceutical company receives large shipments of ibuprofen tablets and uses an acceptance sampling plan. This plan randomly selects and tests 26 tablets, then accepts the whole batch if there is at most one that doesn't meet the required specifications. What is the probability that this whole shipment will be accepted if a particular shipment of thousands of ibuprofen tablets actually has a 15% rate of defects?

(Report answer as a decimal value accurate to four decimal places.)
P(accept shipment) =

Answer 1

0.8475

Explanation:

We can model the number of defective tablets in the shipment as a binomial distribution with parameters $n=26$ (the sample size) and $p=0.15$ (the probability of a defective tablet).

To calculate the probability that the whole shipment will be accepted, we need to find the probability that the number of defective tablets in the sample is at most 1, which means that the shipment meets the required specifications.
