1. A random variable X is normally distribute with a mean of 10 and a standard deviation of 3.
2. A random variable X is normally distributed with a mean of 95 and a standard deviation of 12. If P(A < X < B) = 0.8592, find A and B such that A and B are symmetric about the mean.
3. The weights of a particular species of animal are normally distributed with a mean of 10 pounds and a standard devaition of 2 pounds. If a newborn animal of this species is in the 85th percentile, what it its weight?
