9) Alie detector test is such that when given to an innocent person, the probability of this person being judged guilty is 0.05; on the other hand, when given to a quilty person, the probability of this person being judged innocent is 0.07. Suppose 2% of the people in the population are guilty. a) Given that a person picked at random is judged innocent, what is the probability that the person is indeed innocent ? Given that a person picked...
The probability that a person selected at random from a population will exhibit the symptoms of lung cancer is 0.1. The probability that a person who was found to have the symptoms also has lung cancer is 0.3 and the probability that a person who was found not to have any symptoms also has lung cancer is 0.1. What is the probability that a person has the symptoms, given that they have lung cancer?

show your work 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....
