A recent survey reported that 60% of 18- to 29-year-olds in a certain country own tablets. Using the binomial distribution, complete parts (a) through (e) below. a. vvnat IS the probability Ina! \"1 me next SIX 'I- [0 zuyearotas surveyed, Your Will own a IaDIel'.' The probability is E. (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 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 E. (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-year-olds 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 D. (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.) a. What assumptions do you need to make in (a) through (0)? Select all that apply. E] A. Each observation is classied into one of two mutually exclusive and collectively exhaustive categories. E] B. The outcome of any observation is dependent of the outcome of any other observation. E] c. The outcome of any observation is independent of the outcome of any other observation. E] D. The probability of an observation being classied as the event of interest, 1:, is constant from observation to observation
