Answer #1

I think that the sample sizes are not the same for all 5 tests because the degree of freedom for each of the five tests are different, which means that the sample sizes must be different for each of the five tests.

degree of freedom for these tests is given df = (n1+n2) - 2

n1 denote sample size from first sample and n2 denote sample size from second sample.

So, difference between the degree of freedoms is the main reason due to which I think that the sample sizes are not the same for all 5 tests.
