Question

A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 299 vinyl gloves, 60% leaked viruses. Among 299 latex gloves, 5% leaked viruses. See the accompanying display of the technology results. 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. Identify null, alternative hypothesis, test statistic, and P-value.

(Table at bottom of the question)

Technology results:

Pooled proportion: 0.33

Test statistic, z: 14.2190

Critical z: 1.6449

P-value: 0.0000

90% Confidence interval: 0.4938438 < p1 - p2 < 0.5964572

Answer #1

A newspaper published an article about a study in which
researchers subjected laboratory gloves to stress. Among 223 vinyl
gloves, 65% leaked viruses. Among 223 latex gloves, 6% 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.
i need the test statistic and possibly the p-value

A newspaper published an article about a study in which
researchers subjected laboratory gloves to stress. Among 206 vinyl
gloves, 66% leaked viruses. Among 206 latex gloves, 12% 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.
-What are the null and alternative
hypotheses?
-z value
-p-value

A newspaper published an article about a study in which
researchers subjected laboratory gloves to stress. Among 216 vinyl
gloves, 64% leaked viruses. Among 216 latex gloves, 99% 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.
Identify the test statistic.

A newspaper published an article about a study in which
researchers subjected laboratory gloves to stress. Among 271 vinyl
gloves, 66% leaked viruses. Among 271 latex gloves, 10% 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.
