Reаd аnd аnswer the fоllоwing questiоn. If a calculation is not possible, type NA. The population of weights for men attending a local health club is normally distributed with a mean of 178 lbs and a standard deviation of 30 lbs. An elevator in the health club is limited to 35 occupants, but it will be overloaded if the total weight is in excess of 6685 lbs.Assume that there are 35 men in the elevator. What is the average weight per man that, beyond which, the elevator would be considered overloaded? average weight = [a] lbs What is the probability that one randomly selected male health club member will exceed this weight? P(one man exceeds) = [b] round to 2 decimal places If we assume that 35 male occupants in the elevator are the result of a random selection, find the probability that the elevator will be overloaded? P(elevator overloaded) = [c] round to 4 decimal places
