Transcribed Image Text:A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 210 vinyl gloves, 62% leaked viruses. Among 210 latex
gloves, 11% 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?
A. Ho: P1 > P2
H1: P1 = P2
O C. Ho: P1 = P2
H1:P1 > P2
О В. Но: Р1 - P2
H1:Pq # P2
O E. Ho: P1 <P2
H1: P1 = P2
O F. Ho: P1 = P;
H1: P1 <P2
D. Ho: P1 # P2
H1: P1 = P2
Identify the test statistic.
(Round to two decimal places as needed.)
Identify the P-value.
(Round to three decimal places as needed.)
What is the conclusion for this test?
The P-value is
the significance level a, so
the null hypothesis. There is
evidence to support the claim that vinyl gloves have a greater
virus leak rate than latex gloves.
