The manufacturer of Beta cars claims that the proportion of adults in a certain town who own a Beta car is 5 1. Raju suspects that the true proportion is less than 5 1. He plans to carry out a hypothesis test using a random sample of 40 adults from the town. If fewer than 4 of these adults own a Beta car, he will conclude that the true proportion is less than 5 1.
