1, if right-handed 0, if left-handed. 10. Suppose the probability for a person to be right-handed is p. Let X = (a) What distribution does X follow? (b) A scientist selected a random sample of 1000 people. Let Y be the number of people who are right-handed, what distribution does Y follow? (c) This scientist found out that among the 1000 people, 100 are right-handed. He then estimated p to be 0.1. What theorem justifies his conclusion....
