A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 262
vinyl gloves, 68% leaked viruses. Among 262 latex gloves, 11% 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.
