1. A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 213 vinyl gloves, 63% leaked viruses. Among 213 latex gloves, 9% leaked viruses. Using the accompanying display of the technology results, and using a 0.10 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. technology results: Pooled proportion: 0.36 Test statistic, z: 11.6982 Critical z: 1.2816 P-value:...
