HI, I have 3 major problems in the following On 36% of all winters, Des Moines experiences three major snowstorms. On 16% of all winters, Des Moines experiences one major snowstorm. Des Moines experiences four major snowstorms on 22% of all winters and experiences no major snowstorms on 4% of all winters. On 17% of all winters, Des Moines experiences two major snowstorms. Suppose that Des Moines never experiences more than five major snowstorms in any winter. 14. Des Moines averages how many major snowstorms each winter? (a) 3 (b) 30 (c) 27.10 (d) 4.22 (e) None of the answers is correct 15. Des Moines averages how many major snowstorms over a ten-year period? (a) 3 (b) 30 (c) 27.10 (d) 4.22 (e) None of the answers is correct The polling firm Gallup, Inc. uses a random-digit dialing machine to assist in making telephone surveys. In fact, 23% of calls made by the machine reach a “live person” who answers the phone. Any given work day is considered more successful if the machine reaches more live persons on that day. Suppose that the machine makes 300 calls a day. 12. What’s the minimum number of live persons reached on the 84% of all days which are most successful? (Round to the nearest person.) (a) About 62 persons (b) About 76 persons (c) About 16 persons (d) About 122 persons (e) None of the answers is correct 13. What’s the maximum number of live persons reached on the 84% of all days which are least successful? (Round to the nearest person.) (a) About 62 persons (b) About 76 persons (c) About 16 persons (d) About 122 persons (e) None of the answers is correct Two manufacturing processes can be used to produce computer chips which regulate engine performance in new cars: Process A and Process B. The time required for Process A to produce one computer chip is uniformly distributed between 3.0 and 5.5 minutes; the time required for Process B is uniformly distributed between 2.6 and 5.3 minutes. What percentage of chips are produced in less than 4 minutes with Process A? (a) 50.00 (b) 49.15 (c) 60.00 (d) 51.85 (e) None of the answers is correct to the second decimal place. What percentage of chips are produced in less than 4 minutes with Process B? (a) 50.00 (b) 49.15 (c) 60.00 (d) 51.85 (e) None of the answers is correct to the second decimal place. The chip maker has two manufacturing goals: that at least 95% of chips are produced in less than 5.4 minutes, and that average time required to produce chips is no more than 4 minutes. Which processes satisfy these goals? (a) Only Process A satisfies these goals. (b) Only Process B satisfies these goals. (c) Both Process A and Process B satisfy these goals. (d) Neither Process A nor Process B satisfies these goals. (e) It is impossible to determine whether either process satisfies these goals.
