A company that manufactures and bottles apple juice has a machine that automatically fills 16-ounce bottles. There is, however, some variation in the exact amount of juice dispensed into each bottle by the machine. Over a long period of time, the average amount dispensed into the bottle was 16 ounces, but there is a standard deviation of 1 ounce in these measurements. If the amount of liquid per bottle can be assumed to have a normal distribution, find the percentage of bottles that will either be overfilled or underfilled by at least 0.5 ounce. A. 30.85%
B. 38.30%
C. 61.70%
