A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 230 vinyl gloves, 57% leaked viruses. Among 230 latex gloves, 9% leaked viruses. Using the accompanying display of the technology results, and using a 0.05 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. A Click the icon to view the technology results. U A. Ho: P = P2 H,: P, > P2 UB. Mo: Pi = P2 H,: P, # P2 t. Ho: P, = P2 Technology Results O D.

In a study to determine if the nitrogen content of the soil in Wyoming is less than the nitrogen content of the soil in North Dakota, 27 independent random soil samples from Wyoming and 32 from North Dakota were taken. Given the testing statistics below, determine if the data provides sufficient evidence to conclude that the nitrogen content of the soil in Wyoming is less than the nitrogen content of the soil in North Dakota, at the 1% significance level. H0:μw≥μnHa:μw<μn The test statistic is t0=−1.53 t0.01=−2.663
In a study to determine if the nitrogen content of the soil in Wyoming is significantly different from the nitrogen content of the soil in North Dakota, 34 independent random soil samples from Wyoming and 36 from North Dakota were taken. Given the testing statistics below, determine if the data provides sufficient evidence to conclude that the nitrogen content of the soil in Wyoming is significantly different from the nitrogen content of the soil in North Dakota, at the 1% significance level.

A grassroots group opposed to a proposed increase in the gas tax claimed that the increase would hurt working-class people the most, since they commute the farthest to work. Suppose that the group randomly surveyed 24 individuals and asked them their daily one-way commuting mileage. The results are in Table below. Using a 5% significance level, test the hypothesis that the three mean commuting mileages are the same. working-class professional (middle incomes) professional (wealthy) 17.8 16.5 8.5 26.7 17.4 6.3 49.4 22.0 4.6 9.4 7.4 12.6 65.4 9.4 11.0 47.1 2.1 28.6 19.5 6.4 15.4 51.2 13.9 9.3
