NOTE: Answers using z-scores rounded to 3 (or more) decimal places will work for this problem. The population of weights for men attending a local health club is normally distributed with a mean of 171-lbs and a standard deviation of 26-lbs. An elevator in the health club is limited to 33 occupants, but it will be overloaded if the total weight is in excess of 6105-lbs. Assume that there are 33 men in the elevator. What is the average weight beyond which the elevator would be considered overloaded?

1. A) A population of values has a normal distribution with μ=8.2μ=8.2 and σ=55.6σ=55.6. You intend to draw a random sample of size n=249n=249. Find the probability that a sample of size n=249n=249 is randomly selected with a mean less than 16.3. P(M < 16.3) = ? Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted. B) A population of values has a normal distribution...
