Instructor-created question Question Help A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 283 vinyl gloves, 60% leaked viruses. Among 283 latex gloves, 12% 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. Click the icon to view the technology results. Technology Results X What are the null and alternative hypotheses? O A.
