The t test for the mean difference between two related populations assumes that the population distribution of differences are approximately normal. This assumption is crucial as it impacts the validity of the test results. If the distribution is not approximately normal, then other statistical tests may be more appropriate. The other options listed, such as population sizes or sample sizes, are not assumptions for this specific test.
