Question 1188969: Suppose that a doorway being constructed is to be used by a class of people
whose heights are normally distributed with mean 70 cms. and standard deviation 3
cms. How long may the doorway be without causing more than 25% of the people
to bump their heads? If the height of the doorway is fixed at 76 cms., how many
persons out of 5000 are expected to bump their heads? (Given Φ(2) = 0.4762). Answer by ikleyn(52890) (Show Source):
