From our last lesson about z-score, we know that z-score corresponds to different proportions in a normal distribution. It might be handy to remember that: 1) 68.26% of all observed data values will fall within ONE standard deviation from the mean (that is to the left and to the right). 2) 95.44% of all observed data values will fall within TWO standard deviations from the the mean (again, that is to the left and to the right). 3) 99.74% of...

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...
