Answer please and thank you.
![**Research Study on Laboratory Gloves and Virus Leak Rates**
A newspaper article reported on a study wherein researchers tested laboratory gloves for virus leakage under stress conditions. The study details are as follows:
- **Vinyl Gloves**: Out of 276 gloves tested, 68% showed virus leakage.
- **Latex Gloves**: Out of 276 gloves tested, 15% showed virus leakage.
The objective is to test, at a 0.10 significance level, whether vinyl gloves have a higher virus leak rate compared to latex gloves. For this study, vinyl gloves are considered as population 1.
### Null and Alternative Hypotheses
Participants must choose from the following options:
- **Option A**: \( H_0: p_1 > p_2 \) | \( H_1: p_1 = p_2 \)
- **Option B**: \( H_0: p_1 \neq p_2 \) | \( H_1: p_1 = p_2 \)
- **Option C**: \( H_0: p_1 = p_2 \) | \( H_1: p_1 \neq p_2 \)
- **Option D**: \( H_0: p_1 < p_2 \) | \( H_1: p_1 = p_2 \)
- **Option E**: \( H_0: p_1 = p_2 \) | \( H_1: p_1 < p_2 \)
- **Option F**: \( H_0: p_1 = p_2 \) | \( H_1: p_1 > p_2 \)
### Test Statistic and P-Value Identification
- **Identify the Test Statistic**: Input should be rounded to two decimal places.
- **Identify the P-Value**: Input should be rounded to three decimal places.
### Conclusion of the Test
Fill in the following framework based on the findings:
- The P-value is [Value] the significance level \(\alpha\), so [Decision on Null Hypothesis] the null hypothesis. There is [Strength of Evidence] evidence to support the claim that vinyl gloves have a greater virus leak rate than latex gloves.
This study aims to provide insights into the effectiveness of different glove materials in preventing virus transmission in laboratory settings.](https://content.bartleby.com/qna-images/question/2f0fb466-9e5e-42c4-aac7-4119dc8b6f62/45921e45-863e-4468-9fb2-6062410957d8/n3qkljj_thumbnail.png)
