Question

Quizplus · Accepted Answer

When the paired differences are normal, the appropriate distribution for testing the difference between two population means is the Student t-distribution. This is because the paired differences are used to calculate the sample mean difference and the sample standard deviation of the differences, which are used to calculate the t-statistic.
