Problems

To Calculate

1. Use the permutation test to decide whether the contingency table shows a significant association. What is the p-value?

2. Repeat the calculation using the Pearson chi-square statistic instead of the Wald statistic, or vice versa.

To Think About

1. Is slide's 7 suggestion, that you figure out how to implement the permutation test without "expanding all the data", actually possible? If so, what is your method?
