B. Identify the test statistic. ______ C. Identify the P-value. ____ D. What is the conclusion for this test? The P-value is (greater than/less than) the significance level α, so (reject/ fail to reject) the null hypothesis. There is (sufficient/ insufficient) evidence to support the claim that vinyl gloves have a greater virus leak rate than latex gloves.

aps Microsoft Word -... 12) and 13) Hypothesis testing for proportions You must show your work: 1. Clearly state the significance level, sample size, sample proportion 2. Clearly state the null hypothesis and alternative hypothesis 3. Present the test statistics (z-score) and P-value 4. Decided if the null hypothesis should be rejected for the alternative or not. 5. Write out the conclusion to the question. ► The recidivism rate for convicted sex offenders is 15%. A warden suspects that this percent is higher if the sex offender is also a drug addict. Of the 320 convicted sex offenders who were also drug addicts, 58 of them became repeat offenders. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? Select an answer H₁: ? Select an answer ✓ c. The test statistic ? = d. The p-value = e. The p-value is ? ✓ a f. Based on this, we should g. Thus, the final conclusion is that…
