Webt = ( x̄ – μ) / (s / √n) The formula for the two-sample t-test can be derived using the following steps: Step 1: Determine the observed sample mean of the two samples under consideration. The sample means are denoted by x̄ 1 and x̄ 2. Step 2: Next, determine the standard deviation of the two samples, which are denoted by and.
