    More Practice With Normal Distributions. Assign your numbers for mean μ and standard deviation σ. Then select a number "A" below mean μ, and a number "B" above mean μ. Use Appendix Table for the Normal Distribution to find probability that x is between A and B: P (A < x < B). Here are steps to follow: convert A to z score (let's call it za), convert B to z score (let's call it zb).; From Appendix table find...
