Key Points

To establish and evaluate statistical significance testing for the difference between means in two normal populations that exhibit unequal variances.
Theoretical formulation and statistical derivation of hypothesis tests comparing sample means drawn from two independent, normally distributed populations with unequal variances.
Presents statistical criteria to test whether observed differences between group means remain significant when population variances cannot be assumed equal.
Provides a mathematical framework to resolve inference problems arising from variance heterogeneity between two normal sample distributions.
