A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 239 vinyl gloves, 60% leaked viruses. Among 239 latex gloves, 8% leaked viruses. Using the accompanying display of the technology results, and using a 0.01 signicance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. Identify the test statistic. (Round to two decimal places as needed.)
