Question 724006
The quality-control inspector of a production plant will reject a batch of automobile batteries if three or more defectives are found in a random sample of eleven batteries taken from the batch. Suppose the batch contains 5% defective batteries. What is the probability that the batch will be accepted?
------------------
Binomial Problem with n = 11 and p(defect) = 0.05
----
P(0<= x <=2) = binomcdf(11,0.05,2) = 0.0867
