A recent survey reported that 40% of 18' to 29-year-olds in a certain country own tablets. Using the binomial distribution. CONPIEIB park (a) through (6) bEIUW. a. What is the probability that in the next six 18- to 29-year-olds surveyed, four wl own a tablet? The probability is E. (Type an integer or a decimal. Round to four decimal pieces as needed.) b. What is the probability that in the next six 18- to 29-year-olds surveyed. all six will own a tablet? The probability is E. (Type an integer or a decimal. Round to four decimal places as needed.) c. What is the probability that in the next six 18- to 29-year-olds surveyed, at least four will own a tablet? [} The probability is 1:). (Type an integer or a decimal. Round to four decimal places as needed.) d. What are the mean and standard deviation of the number of 18- to 29yearolds who will own a tablet in a survey of six? The mean number of 18- to 29-year-olds who own tablets out of six surveyed is E. (Type an integer or a decimal. Round to four decimal places as needed.) The standard deviation of the number of '18- to 29-year-olds who own tablets out of six surveyed is E. (Type an integer or a decimal. Round to four decimal places as needed.) e. What assumptions do you need to make in (a) through (G)? Select all that apply. E] A. Each observation is classied into one of two mutually exclusive and collectively exhaustive categories. D B.
