A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 291 vinyl? gloves, 65?% leaked viruses. Among 291 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.
