Question

A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 265 vinyl gloves, 57% leaked viruses. Among 265 latex gloves, 5% 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. LOADING... Click the icon to view the technology results. What are the null and alternative hypotheses? A. Upper H 0: p 1equalsp 2 Upper H 1: p 1greater thanp 2 B. Upper H 0: p 1not equalsp 2 Upper H 1: p 1equalsp 2 C. Upper H 0: p 1equalsp 2 Upper H 1: p 1not equalsp 2 D. Upper H 0: p 1equalsp 2 Upper H 1: p 1less thanp 2 E. Upper H 0: p 1greater thanp 2 Upper H 1: p 1equalsp 2 F. Upper H 0: p 1less thanp 2 Upper H 1: p 1equalsp 2 Identify the test statistic. 12.94 (Round to two decimal places as needed.) Identify the P-value. nothing (Round to three decimal places as needed.) What is the conclusion for this test? The P-value is less than the significance level alpha, so reject the null hypothesis. There is sufficient evidence to support the claim that vinyl gloves have a greater virus leak rate than latex gloves.

Answer #1

p1cap = 0.57

p1cap = 0.05

pcap = 0.31

Below are the null and alternative Hypothesis,

Null Hypothesis, H0: p1 = p2

Alternate Hypothesis, Ha: p1 > p2

Test statistic

z = (p1cap - p2cap)/sqrt(pcap * (1-pcap) * (1/N1 + 1/N2))

z = (0.57-0.05)/sqrt(0.31*(1-0.31)*(1/265 + 1/265))

z = 12.94

P-value Approach

P-value = 0

As P-value < 0.01, reject the null hypothesis.

There is sufficient evidence to support the claim that vinyl gloves
have a greater virus leak rate than latex gloves.

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.
