Large counts condition ap stats.

The conditions are Random and Large Counts. The large counts condition is different than the one we use for proportions: the expected counts must be greater than 5. We already calculated the test statistic yesterday but we didn't find the P-value using table C. To use table C we need the degrees of freedom, df = n - 1, where n is the number ...
