Question #3

A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 298 vinyl gloves, 60% leaked viruses. Among 298 latex gloves,

13% leaked viruses. Using the accompanying display of the technology results, and using a

0.01 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1.
