A company surveyed 2,600 North American airline passengers and reported that approximately 60% said that they carry a smartphone when they travel. Suppose that the actual percentage is 60%. Consider randomly selecting ten passengers and define the random variable x to be the number of the ten selected passengers who travel with a smartphone. The probability distribution of x is the binomial distribution with n-10 and p=0.6. (Round your answers to three decimal places.) (a) Calculate p(5). USE SALT P(5)-246 x (b) Calculate P(x 57). P(x 57)= (c) Calculate the probability that more than half of the selected passengers travel with a smartphone.
