Question 924039: Assume X is a random variable with a normal distribution with a mean of 22 and a standard deviation of 3. Use two ways to find the answer to the following problems: one of them is to use the NORMDIST function and the other way is to use the standard normal tables at the back of the textbook. Confirm that the two answers are approximately the same.
