THE FINAL ANSWER IS NOT 0.0568 OR 0.3228 Suppose that the number of customers who enter a supermarket each hour is normally distributed with a mean of 520 and a standard deviation of 210. The supermarket is open 12 hours per day. What is the probability that the total number of customers who enter the supermarket in one day is greater than 7400? (Hint: Calculate the average hourly number of customers necessary to exceed 7400 in one 12-hour day.)
