The weights of male nurses in a hospital are known to be normally distributed with mean ƒÝ = 72 kg and standard deviation ƒã = 7.5 kg. The hospital has a lift (elevator) with a maximum recommended load of 450 kg. Six male nurses enter the lift. Calculate the probability p that their combined weight exceeds the maximum recommended load.

Z = (score-mean)/SEm
Score = 450/6
SEm = SD/√n
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z score.
