Most of the studies in practice concern comparison of the difference of group means. The goal of this study is testing the equality of the means of normal population when the variances are unequal. We compare the performance of the proposed tests such as the generalized F-test (GF), the parametric bootstrap test (PB) and test based on fiducial p-value (FP). Monte Carlo simulation studies are conducted to compare the empirical size and power of these tests.
