Researchers conducted a study comparing the effectiveness of vinyl gloves and latex gloves. Among 245 vinyl gloves, 196 leaked viruses. Among 245 latex gloves, 166 leaked viruses. Use a 0.05 significance level to test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. State the claim, null, and alternative hypothesis. Claim: p1                          p2 HO: p1                                      p2 H1: p1                            p2
