Twenty percent of all telephones of a certain type are submitted for service while under warranty. Of these, 60% can be repaired, whereas the other 40% must be replaced with new units. A company purchases 10 of these telephones for their employees. Let these 10 telephones represent a random sample and let X be the number in the sample that will end up being replaced under warranty if submitted for service. a) What is the probability that a telephone will be replaced if submitted for service? b) Describe why the Binomial distribution is appropriate for the random variable X. c) What is the probability that exactly 2 telephones will end up being replaced under warranty? d) What is the interpretation for P(X s 2) and P(X
