Activity Overview

Students test claims of whether given distributions "fit" theoretical distributions. Students will work through two problems, one in which the theoretical proportions of each category are the same and one in which they are not. Students will use spreadsheets to calculate test statistics and the Integral tool to calculate P-values. They check their calculations by using the chi square goodness-of-fit test.
