All but 4% of the time, a good chip passes the test, but unfortunately, 35% of the bad chips pass the test, too. You have to decide on the basis of one test whether the chip is good or bad. Make this a hypothesis test.

b) Given that a computer fails the test, what would you decide? What if it passes the test? c) How large is a for this test?
