In the previous section, we made the assumption of unequal variances between our two populations. Welch's t-test statistic does not assume that the population variances are equal and can be used whether the population variances are equal or not. The test that assumes equal population variances is referred to as the pooled t-test. Pooling.

Excel Function: Excel provides the function T.TEST to handle the various two-sample t-tests. T.TEST(R1, R2, tails, type) = the p-value of the t-test for the difference between the population means based on samples R1 and R2, where tails = 1 (one-tailed) or 2 (two-tailed) and type takes one of the following values: the samples have paired values.
