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
Based on a Harris Interactive poll, 20% of adults believe in reincarnation. Assume that six adults are
randomly selected, and find the indicated probability.
a) What is the probability that exactly five of the selected adults believe in
reincarnation?
b) What is the probability that all of the selected adults believe in reincarnation?
c) What is probability that at least five of the selected adults believe in reincarnation?
d) If six adults are randomly selected, is five an unusually high number who believe in
reincarnation?
