Exercise

Expected vs. Observed Probabilities

In your console your observed probabilities are saved as obsProb and your expected probabilities are expProb. Enter the names of these data tables into your console and compare the values.

We are testing whether person category is independent of ad preference. Based only on the predicted and observed probabilities (pretend that p-values don't exist!), do these seem to be independent?
