A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 228 vinyl gloves, 57% leaked viruses. Among 228 latex gloves, 11% 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. Pooled proportion: 0.34 Test statistic, z: 10.5783 Critical z: 1.2816 P-value: 0.0000 80% Confidence interval: 0.4199096
