Discussion:
An apple juice producer buys all his apples from a conglomerate of apple growers in one northwest state. The amount of juice squeezed from each of these apples is known to be normally distributed with a mean of 2.25 ounces and a standard deviation of 0.15 ounce.
Q: Between what two values (in ounces) symmetrically distributed around the population mean will 80% of the apples fall?
