A marketing analyst at the IU bookstore wants to know whether students spend more on IU-branded merchandise online or in-store. The analyst collects random samples of purchase amounts from both sales channels. The sample shows that students spend an average of $58.40 online and $63.75 in-store. Assuming the data are approximately normally distributed and the variances are not necessarily equal, a hypothesis test is conducted to determine whether there is a significant difference () in the average spending between online and in-store customers. The test yields a p-value of 0.037. If instead, the marketing analyst tests whether there is a significant difference by more than $3.00, what would happen to the p-value?
