Testing Laboratory Gloves: The New York Times ran an article about a study in which Professor Denise Korniewicz and other John Hopkins researchers subjected laboratory gloves to stress. Among 240 vinyl gloves, 151 gloves leaked virus. Among 240 latex gloves, 17 leaked virus. At the 1% significance level, test the claim that vinyl gloves have a higher virus leak rate than latex gloves. Let: = proportion of vinyl gloves that leaked virus and = proportion of latex gloves that leaked virus.
