An elevator has a placard stating that the maximum capacity is 1272 lb—8 passengers. So, 8 adult male passengers can have a mean weight of up to 1272/8=159 pounds. If the elevator is loaded with 8 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 159 lb. (Assume that weights of males are normally distributed with a mean of 167 lb and a standard deviation of 30 lb.) Does this elevator appear to be safe? Can you help me solve this with a TI 84?

Question

An elevator has a placard stating that the maximum capacity is

1272

lb—8

passengers. So,

adult male passengers can have a mean weight of up to

1272/8=159 pounds.

If the elevator is loaded with

adult male passengers, find the probability that it is overloaded because they have a mean weight greater than

159

lb. (Assume that weights of males are normally distributed with a mean of

167 lb

and a standard deviation of

30 lb.)

Does this elevator appear to be safe?

Can you help me solve this with a TI 84? Im trying to use the "normalcdf" function
