A shopper spends on average 45 minutes in a store with a standard deviation of 12 minutes. Assume the length of time spent shopping in a store is normally distributed. Find the probability a shopper will be in a store between 24 and 54 minutes. If there are 200 shoppers in the store, how many shoppers would you expect will stay in the store between 24 and 54?
