Add to ORKGEstimating the difference between unknown means of two independent populations is a very useful project in many fields of study. Some standard tests or confidence intervals of the difference of two means exist. However, the existing tests are valid only when the two populations have known variances, or unknown but equal variances. The real world hardly ever gives such conditions
