In addition to the metrics discussed in class, we can also use
t-test to evaluate the difference between two models, i.e., to
determine if two sets of performance results are significantly
different from each other. In general, the t-test is a statistical
hypothesis test in which the test statistic follows a Student's
t-distribution under the null hypothesis. Now suppose that we would
like to select between two prediction models, M1 and M2. We have
