Which, if either, is larger, the cumulative distribution of T

1. Which, if either, is larger, the cumulative distribution of T(8) at -3.2 or the cumulative distribution of T(27) at -3.2. Explain your answer. 2. Which, if either, is larger, the cumulative distribution of N(0, 1) at -3.2 or the cumulative distribution of T(8) at -3.2. Explain your answer. 3. If I hope to reject H0, why should I hope that the (estimated) variance of is small?
