Assignment:
In computing sample size for estimating population proportions, the formula involves p(1-p) (where we don't know p). We use p = ½ if we don't know anything about it, since that is a "worst case". Find the values of p(1-p) for p=.01, .02, .05, .10, .15, .20, .30, .40., .50, .60, .70,.80, .85, .90, .95, .98, and.99. Be prepared to graph these (this is trivial to do with Excel), and be prepared to talk about the graph.
Provide complete and step by step solution for the question and show calculations and use formulas.
