1. The problem statement, all variables and given/known data Suppose that the weights of airline passenger bags are normally distributed with a mean of 48.14 pounds and a standard deviation of 3.71 pounds. Let X represent the weight of a randomly selected bag. For what value of c is P(E(X) - c < X < E(X) + c)=0.95? Give your answer to four decimal places. 2. Relevant equations I have statcrunch and a normal, poisson, and gamma calculator. 3. The attempt at a solution For this I assume we are looking for a standard deviation. I've been playing with a calculator but honestly I just need help getting started. thanks.
