A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 238 vinyl gloves, 60% leaked viruses. Among 238 latex gloves, 15% leaked viruses. Using the accompanying display of 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.
