A maintainability goal of 90 percent restoration on all
automotive transmiSSIOn failures within 8 hours has been established for a
repair shop. If 80 percent is unacceptable, determine the accept and reject
region for a maintainability demonstration using the sequential binomial test.
Set the probability of both a Type I and Type II error to 10 percent. If after
observing 30 repairs, 27 were completed within 8 hours, what is the decision?
If after 60 repairs, 55 were completed within 8 hours?
