Read and answer the following question. 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 183 lbs and a standard deviation of 26 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 6860 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

A group was tested for drugs. The table shows the results of the test along with actual drug use. Test Positive Test Negative Total Used Dugs 26 13 39 No Drug Use 25 189 214 Total 51 202 253 Let D = event “Used Drugs”, N = event “No Drug Use”, + be “Test positive”, and finally – be “Test negative”Round each answer to 4 decimal places. (D or +)= [a] (N and +) = [b] (N

The population of weights for men attending a local health club is normally distributed with a mean of 182 lbs and a standard deviation of 30 lbs. An elevator in the health club is limited to 34 occupants, but it will be overloaded if the total weight is in excess of 6698 lbs.Assume that there are 34 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?
