A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 261 vinyl gloves, 60% leaked viruses. Among 261 latex gloves, 12% 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. Pooled proportion: 0.36 Test statistic, z: 11.4104 Critical z: 2.3264 P-value: 0.0000 98% Confidence interval: 0.3943331

Question
A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 261 vinyl gloves, 60% leaked viruses. Among 261 latex gloves, 12% 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.
Pooled proportion: 0.36
Test statistic, z: 11.4104
Critical z: 2.3264
P-value: 0.0000
98% Confidence interval:
0.3943331<p1−p2< 0.5635213
Identify the test statistic.
Identify the P-value.
