SOLUTION: Use Standard Normal Distribution to find probability P(z > 2). Remember: Appendix Table II and Excel function Normsdist(z) give you P(z < 2). Use formula: P(z>2) = 1

Question 1047028: Use Standard Normal Distribution to find probability P(z > 2).
Remember: Appendix Table II and Excel function Normsdist(z) give you P(z < 2).
Use formula: P(z>2) = 1 - P(z<2)

0.8000

0.2010

0.9780

0.0228

Probability of z>2 is small. With the empiric rule, one would predict it would be about 2.5%
In fact, it is 0.0228.
P (z<2) is 0.9772.
