Answer 1

Answer Date: 10/11/2019 To test the hypothesis is that vinyl gloves have a greater virus leak rate than latex gloves at 10% significance level. The null and alternative hypothesis is, H : P: = P2 H:P> P2 The answer is B. The z-test statistics is, From Technology output, the z-test statistics is 11.21 The p-value for this test is, From Technology output, the p-value for this test is 10.000). Decision

The conclusion is that the p-value in this context is less than 0.10 which is 0.000, so reject the null hypothesis at 10% level of significance. There is sufficient evidence to indicate that vinyl gloves have a greater virus leak rate than latex gloves. The result is statistically significant.
