A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 238 vinylgloves, 62% leaked viruses. Among 238 latexgloves, 12% leaked viruses. Using the accompanying display of the technologyresults, and using a 0.05 significancelevel, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1.
