The weight of items produced by a machine is normally distributed with a mean of 8 ounces and a standard deviation of 2 ounces.
What is the probability that a randomly selected item will weigh more than 10 ounces?
z-score = 1. Using the table, z-score = 1, the area to the left is .8413. So the area to the right, the probability bigger than the z-score is, 1-.8413.
