An elevator has a placard stating that the maximum capacity is 1344 lb-8 passengers.
An elevator has a placard stating that the maximum capacity is 1344 lb-8 passengers. So, 8 adult male passengers can have a mean weight of up to 1344/8=168 pounds. If the elevator is loaded with 8 adult male passengers, find the probability that it is overlioaded because they have a mean weight greater than 168 lb. (Assume that weights of males are normally distributed with a mean of 177 lb and a standard deviation of 25 lb.) Does this elevator...

An elevator has a placard stating that the maximum capacity is 1600lb—10 passengers. So, 10 adult male passengers can have a mean weight of up to 1600/10=160 pounds. If the elevator is loaded with 10 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 160 lb. (Assume that weights of males are normally distributed with a mean of 168 lb and a standard deviation of 28 lb.) Does this elevator appear...
