Suppose that an airline uses a seat width of 17.9 in. Assume men have hip breadths that are normally distributed with a mean of 15.2in. And a standard deviation of 1.2 in (a) Find the probability that if an individual man is randomly selected, his hip breadth will be greater than 17.9 in (b) If a plane is filled with 131 randomly selected men, find the probability that these men have a mean hip breadth greater than 17.9 in
