Hey Gang,
So I feel like I've gotten the hang of sampling distribution so far, but I've encountered a question thats really throwing my brain through a loop trying to find the answer to and my online class doesn't really cover how to approach these questions Anyways, heres the question:
An elevator company has conducted a study and determined the average adult weight is 65 kg with a standard deviation of 15 kg. The distribution is approximately normally distributed.
a. The company has decided that the elevator will have a capacity of 5 people and a maximum load of 475 kg. What is the probability that load will be exceeded if there are 5 people in the elevator?
So, looking at the solution, I know the answer is a Z score of 4.47, and I've tried to reverse engineer this the best I could, but I still cant figure it out! Any help is appreciated!
