Estimate the median difference in textbook prices
Suppose instead of the mean, we want to estimate the median difference in prices of the same textbook at the UCLA bookstore and on Amazon. You can't do this using a t-test, as the Central Limit Theorem only talks about means, not medians. You'll use an infer pipeline to estimate the median.
