Let the variable X denotes weight of men.
The variable X follows Normal distribution with mean 165 lb and standard deviation 24 lb.
We have to find the maximum total allowable weight if we want 0.975 probability that this maximum will not be exceeded when 15 males are randomly selected.
That is we have to find such that,
Hence,
That is, P(Z < z) = 0.005
Using standard normal table we find z score for the area 0.005.
Hence, z = 2.58
Therefore,
Hence, maximum weight = 181 lb

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 167 lb and a standard deviation or 25 lb. You need to design an elevator that will safely carry 18 people. Assuming a worst case scenario...

An elevator has a placard stating that the maximum capacity is 2295 lb-15 passengers so 15 adult male passengers get have a mean way up up to 2295÷15 = 153 pounds in the elevator is loaded with 15 adult male passengers find the probability that it is overloaded because they have a mean way greater than 153 pounds (assume that weight of males are normally distributed with a mean of 161 pounds and a standard deviation of 34 pounds )does...
An elevator has a placard stating that the maximum capacity is 1848 11—12 passengers. So, 12 adult male passengers can have a mean weight of up to 1848 / 12 = 154 pounds. If the elevator is loaded with 12 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 154 lb. (Assume that weights of males are normally distributed with a mean of 160 lb and a standard deviation of 30...
An elevator has a placard stating that the maximum capacity is 1320 lb- 8 passengers.? So, 8 adult male passengers can have a mean weight of up to 1320/8=165 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 165 lb.? (Assume that weights of males are normally distributed with a mean of 172 lb and a standard deviation of 33 lb?.) Does this...
An elevator has a placard stating that the maximum capacity is1610 lb—10 passengers. So,10 adult male passengers can have a mean weight of up to1610/10=161 pounds. If the elevator is loaded with10 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than161 lb. (Assume that weights of males are normally distributed with a mean of170 lb and a standard deviation of32 lb.) Does this elevator appear to be safe?A) The probability the...
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 1610 lb---10 passengers. So, 10 adult male passengers can have a mean weight of up to 1610 divided by 10 = 161 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 161lb. (Assume that weights of males are normally distributed with a mean of 165 lb and a standard deviation of 35...
An elevator has a placard stating that the maximum capacity is 12641264 lb long dash—88 passengers. So, 88 adult male passengers can have a mean weight of up to 1264 divided by 8 equals 158 pounds.1264/8=158 pounds. If the elevator is loaded with 88 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 158158 lb. (Assume that weights of males are normally distributed with a mean of 165 lb165 lb and...
An elevator has a placard stating that the maximum capacity is 1700 lb-10 passengers. So, 10 adult male passengers can have a mean weight of up to 1700/10 170 pounds. If the elevator loaded with 10 adult males l a ar to be hat it is overloaded because they have a mean weight areater than 170 lb. (Assume that weights of males are normally distributed with a mean of 175 lb and a standard deviation of 25 lb.) Does The...
