6) Suppose that an airline uses a seat width of 16.1 in. Assume men have hip breadths that are normally distributed with a mean of 14.3 in. and a standard deviation of 1 in.
(A) Find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.1 in.
The probability is: 0.0359
(B) If a plane is filled with 114 randomly selected men, find the probability that these men have a mean hip breadth greater than 16.1 in.
The probability is:
