... The degrees of freedom is equal to the degrees of freedom for MSE (MSE is used to estimate s2). Since MSE is made up of two estimates of s2 (one for each sample), the df for MSE is the sum of the df for these two estimates. Therefore, the df for MSE is (n -1) + (n - 1) = 49 + 49 = 98.A t-table shows ...
