A recent survey reported that 62% of 18- to 29year-olds in a certain country own tablets. Using the binomial distribution, complete parts (a) through (e) below. @ a. What is the probability that in the next six 18- to 29-year-olds surveyed, four will own a tablet? The probability is (Type an integer or a decimal. Round to four decimal places 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 . (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 mblet'? The probability is (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 29-yearolds 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 (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 :|. (Type an integer or a decimal. Round to four decimal places as needed.) a. What assumptions do you need to make in (a) through (c)? Select all that apply. E] A. Each observation is classied into one of two mutually exclusive and collectively exhaustive categories. E] B. The probability of an observation being classied as the event of interest, at, is constant from observation to observation. E] C. The outcome of any observation is dependent of the outcome of any other observation. E] D. The outcome of any observation is independent of the outcome of any other observation
