American households increasingly rely on cell phones as their exclusive telephone service. It is reported that 49.2% of American households still have landline phone service. We decide to randomly call eight households and ask if the home has a landline phone. A. What is the probability that exactly five of the households in the sampled group have a landline phone service? ROUND YOUR ANSWER TO FOUR DECIMAL PLACES B. Given the probability distribution, what is the mean number of households with landline service? ROUND YOUR ANSWER TO 3 DECIMAL PLACES C. What is the variance of the probability distribution of the number of households with landline service? ROUND YOUR ANSWER TO 3 DECIMAL PLACES
