Determine the following for a standard normal distribution:

A. What percent of the area under the curve is within 1 standard deviation of the mean?

That is, find P(-1 less than or equal to Z less than or equal to1)

B. What percent of the area are under the curve is within 2 standard deviations of the mean?

That is, find P(-2 less than or equal to Z less than or equal to 2).

C. What percent of the area under the curve is within 3 standard deviations of the mean?

That is, find P(-3 less than or equal to Z less than or equal to 3).

D. Explain how the values from (a)-(c) are related to the Empirical Rule.
