BINOMIAL PROBABILITIES 1 2 yes no 3 yes no 4 no yes 5 6 7 8 Start After verifying that you have a binomial probability problem, identify n , p , q . Can problem be solved using the Binominal Table (Is n 15 and is p available) Use Binominal Probability Table (Table A-1, in Appendix A) Can the problem be easily solved with the binomial probability formula? Use binomial probability formula. P(x) = n C x p x q n-x Or Graphing Calculator: binompdf (n,p,x) Are np 5 & nq 5 both true? Normal Approximation to a Binominal Probability Compute m = np and s = npq Draw the normal curve, label the points and shade the

Unformatted text preview: desired region representing the probability to be found. Be sure to include the Continuity Correction Factor . (Remember the discrete value x is adjusted for continuity correction by adding and subtracting 0.5 to the value). Calculate the Z-scores: x m s-Ζ = where m and s are the values already found and x is the value you adjusted for the Continuity Correction. Look up the Areas from the Z -Table (Standard Normal Distribution, Table A-2 in the front of text). Then determine the Probability from the shaded Areas....
