On the following pages you are presented with five problems. Your job is to examine the output and discuss whether there is a statistically significant relationship between the two variables, the pattern or direction of the relationship if the relationship is significant, and the strength of the relationship if the relationship is significant. AS you discuss the strength of the relationship, you will rely on an appropriate measure of association from those that have been given. For that determination, you will need to appropriately determine the level of measurement of each of the variables being examined. Please use the Measures of Association Chart I provided to help you with your determination. You may write your responses on a separate document or next to the problems on this one.

Suppose six individuals, within your criteria, are randomly selected. Show or explain your thinking for each problem. (Note: This is a binomial probability from Section 5.2, they either have insurance or they do not.) A. Let having insurance be a success. State the values of your p, q, and n for your chosen condition. Explain your thinking. (For my example, if 22% do not have insurance, then that is my q (failure) value, my p=0.78, q=0.22, n-6 (6 individuals are randomly selected in this problem). B.
