- It is common lore in the Adirondack mountain region of New York that Avon’s Skin So Soft hand lotion is a very effective repellant for black flies, Simulium venustum. To test this claim volunteers applied fixed amounts of a commercial repellant, N,N- diethyl-meta-toluamide (DEET) 20% (Treatment I), or Skin So Soft hand lotion (Treatment II) to their hand and arm, placing it in a chamber with 50 hungry black flies. The time until first bite in minutes is recorded below. Treatment I 5, 14, 6, 8, 8, 15, 13, 2 TreatmentII 3, 7, 10, 49, 2, 38, 6, 9 Are the repellants significantly different in their efficacy? Analyze using the Wilcoxon rank-sum test.The power takeoff driveline on tractors used in agriculture is a potentially serious hazard to operators of farm equipment. The driveline is covered by a shield in new tractors, but for a variety of reasons, the shield is often missing on older tractors. Two type of shields are the bolt-on and the flip- up. It was believed that the bolt-on shield was perceived as a nuisance by the operators and deliberately removed, but the flip-up shield is easily lifted for inspection and maintenance and may be left in place. In a study initiated by the National Safety Council of the U.S., a sample of older tractors with both types of shields was taken to see what proportion were removed. Of 183 tractors designed to have bolt-on shields, 35 had been removed. Of the 136 tractors with flip-up shields, 15 were removed. We wish to test the hypothesis H: Pb= PJ vs A: Pb ≠ f. Pl where Pb and Pꬵ are the proportion of tractors with the bolt-on and flip-up shields removed, respectively. The test-statistic is…lineer sistemin varsa çözümünü bulunuz.

- To determine the effectiveness of an oil additive, a testing firm purchased two cars of the same make, year, and model, and drove each a distance of 30,000 miles using the same kind of gasoline, the same kind of oil, the same driver, under the same road conditions. The oil in one engine included the additive, whereas the oil in the other engine did not. At the end of the test, the engines of both cars were dismantled, and it was found that the engine that contained the additive had less wear. The testing firm concluded that the oil additive caused the reduced wear.Team Yds/Att Int/Att Win% Arizona Cardinals 6.5 0.042 50.0 Atlanta Falcons 7.1 0.022 62.5 Carolina Panthers 7.4 0.033 37.5 Cincinnati Bengals 6.2 0.026 56.3 Detroit Lions 7.2 0.024 62.5 Green Bay Packers 8.9 0.014 93.8 Houstan Texans 7.5 0.019 62.5 Indianapolis Colts 5.6 0.026 12.5 Jacksonville Jaguars 4.6 0.032 31.3 Minnesota Vikings 5.8 0.033 18.8 New England Patriots 8.3 0.020 81.3 New Orleans Saints 8.1 0.021 81.3 Oakland Raiders 7.6 0.044 50.0 San Francisco 49ers 6.5 0.011 81.3 Tennessee Titans 6.7 0.024 56.3 Washington Redskins 6.4 0.041 31.3In 1995, O.J. Simpson (commonly known as “The Juice”) was charged with the murders of Nichole BrownSimpson and Ron Goldman in what has been referred to as the trial of the century. It is commonly known that O.J. Simpson was acquitted on both charges of murder in this case, on the famous “the gloves don’t fit” defense. To this day, people still debate whether or not O.J. Simpson did or did not commit these crimes. Suppose that O.J. Simpson did, in fact, commit the murders. In the context of hypothesis testing, what kind of error was committed by the jury? Write a brief explanation of which kind of error and why.
