Let $p$ be the probability that a coin will fall head in a single toss in order to test $H_0 : p = 1/2$ against $H_1 : p = 3/4$. The coin is tossed 5 times and $H_0$ is rejected if more than 3 heads are obtained. Then the probability of Type-I error is:

Thirty men and thirty women with knee pain were subjects in an experiment to determine the effectiveness of a new pain medication. Fifteen of the 30 men and 15 of the 30 women were chosen randomly to receive the new drug. The remaining 15 men and 15 women received a placebo. The decrease in pain was measured for each subject. Then the design of experiment is
