Suppose we use Pearson's Chi-Squared test for a data set with variables: did a customer churn (yes/no) and location (north/south/east/west). We obtain a p-value of 0.0004 What do we conclude?
(a) The number of people who churn is about the same in all locations.
(b) The number of people who churn is different in different locations.
(c) The chances that a customer will churn is not the same in all locations.
(d) The chances that a customer will churn is about the same in all locations.
