Identify the test statistics, P-value, and what is the conclusion for this test?? There are 4 total parts to this question.
A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 249 vinyl gloves, 59% leaked viruses. Among 249 latex gloves, 9% leaked viruses. Using the accompanying display of the technology results, and using a 0.05 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. What are the null and alternative hypotheses? O B. Ho P1 = P2 H: P #P2 O C. Ho P1 = P2 H, P, > P2 CC O A.
