A fitness company is building a 20-story high-rise. Architects building the high-rise know that women working for the company have weights that are normally distributed with a mean of 143 lb and a standard deviation of 29 lb, and men working for the company have weights that are normally distributed with a mean of 180 lb and a standard deviation or 27 lb. You need to design an elevator that will safely carry 16 people. Assuming a worst case scenario of 16 male passengers, find the maximum total allowable weight if we want a 0.98 probability that this maximum will not be exceeded when 16 males are randomly selected. maximum weight =_________ -lb Round to the nearest pound. Answers obtained using exact z-scores or z-scores rounded to 2 decimal places are accepted.
