For each of the following tables, calculate the obtained chi square. (HINT: Calculate the expected frequencies for each cell with Formula 11.2.

Double-check to make sure you are using the correct row and column marginals for each cell. It may be helpful to record the expected frequencies in table format as well—see Tables 11.2, 11.4, and 11.7.

Next, use a computational table to organize the calculation for Formula 11.1—see Tables
