Question

A recent poll indicated that about 79% of U.S. households had access to a high-speed Internet connection. a. Suppose 100 households were randomly selected from the United States. How many of the households would you expect to have access to a high-speed Internet connection? b. If 20 households are selected randomly, what is the probability that exactly 14 have high-speed access? c. If 20 households are selected randomly, what is the probability that 14 or fewer have high-speed access? c. If 20 households are selected randomly, what is the probability that 14 or fewer have high-speed access? The probability that 14 or fewer households have high-speed access is (Type an integer or decimal. Round to three decimal places as needed.)
