Question:
Find a binomial acceptance testing plan to demonstrate a reliability of 0.98. An
unacceptable reliability is 0.90. The risk of incorrectly accepting or incorrectly rejecting
should be less than 10 percent. What is the minimum sampling size for which both risks are less than 5 percent. Hint: Binomial probabilities can be computed recursively
using
1-Rn-i
Pr{X = i + I} = R i + l Pr{X = i}
where X is the number of failures, I - R is the probability of a failure and n is the
number on test. Numerical problems encountered with large factorials can therefore
be avoided. You are encouraged to prove the foregoing relationship before using it.
