Modus Ponens, 2, 3 Conjunction, 4, 5 7 -(r V q) de Morgan, 6 Which of the following is the correct missing line? O P d- O O rTony Soprano, leader of the Soprano crime syndicate of NJ, was killed by one of his own henchmen. Detective Vin interviews the men and determines that all were lying except for one, based on what he remembers from Hall250 . He has deduced who killed Tony on the basis of the following statements: Bobby: Ralph killed Tony. Silvo: Paulie didn’t kill Tony. Ralph: Paulie was shooting craps with Bobby when Tony was knocked off. Paulie: Ralph didn’t kill Tony. Who killed Tony? Explain your logic.In a study of pain relievers, 25 people were given product A, and 16 experienced relief. In the same study, 100 people were given product B, and 53 experienced relief. Fill in the blanks of the statement below to make the statement the most reasonable possible. Product v performed worse in the study because % failed to get relief with this product, whereas only O % failed to get relief with Product ?

- I need #11 and #13 DIRECTIONS: For each proof, you must include (i.e., write) the premises in that proof. I do not want to see any proofs without premises. Do not use any transformation rules (e.g. contraposition) in your proof other than DN. Only use the eight inference rules. YOU CANNOT USE CONDITIONAL PROOF (CP), INDIRECT PROOF (IP), OR ASSUMED PREMISES (AP). You will lose points if you use any of the inference rules Resolution, Contradiction, Transposition,Show that (a) if P(A) = P(B) = P(AB), then P(ABUBA) = 0; (b) if P(A) = P(B) = 1, then P(AB) = 1.A college professor conducted a survey in order to assess how much money nursing majors spend on course material compared to all other majors. To do so, she selected a random sample of 34 students. Each student was classified as a nursing major or as a non-nursing major. They were then asked how much they spent on books and other materials required for their courses this semester. Here are parallel boxplots summarizing the responses: Based upon the boxplots, which of the following statements cannot be concluded? (A) The range of the distribution of the cost of course materials for nursing majors is about the same as that of non-nursing majors. (B) The maximum cost for non-nursing majors is greater than the median cost for nursing majors. (C) The variability of the cost of course materials for the middle 50% of nursing majors is greater than the variability of the middle 50% for non-nursing majors. (D) The median cost of course materials for nursing majors is over $300 more than…
