The recidivism rate for convicted sex offenders is 16%. A warden suspects that this percent is higher if thesex offender is also a drug addict. Of the 304 convicted sex offenders who were also drug addicts, 55 ofthem became repeat offenders. What can be concluded at the a = 0.10 level of significance?a. For this study, we should use z-test for a population proportion vb. The null and alternative hypotheses would be:Но: | ру0.16(please enter a decimal)%3D=o 0.16H1: p v(Please enter a decimal)c. The test statistic z v(please show your answer to 3 decimal places.)d. The p-value =(Please show your answer to 4 decimal places.)e. The p-value is > vf. Based on this, we should fail to rejectthe null hypothesis.g. Thus, the final conclusion is that ...O The data suggest the populaton proportion is significantly higher than 16% at a = 0.10, sothere is statistically significant evidence to conclude that the population proportion ofconvicted sex offender drug addicts who become repeat offenders is higher than 16%.O The data suggest the population proportion is not significantly higher than 16% at a = 0.10, sothere is statistically significant evidence to conclude that the population proportion of

A college chemistry instructor thinks the use of embedded tutors will improve the success rate in introductory chemistry courses. The passing rate for introductory chemistry is 73%. During one semester, 200 students were enrolled in introductory chemistry courses with an embedded tutor. Of these 200 students, 162 passed the course. The instructor carried out a hypothesis test and found that the observed value of the test statistic was 2.55. The p-value associated with this test statistic is 0.0054. Explain the meaning of the p-value in this context. Based on this result, should the instructor believe the success rate has improved? State the hypotheses that were used for the test Choose the correct answer below. OA. Ho: p=0.73 and Ha: p>0.73 OB. Ho: p0.73 OC. Ho p=0.73 and Ha: p0.73 and Ha: p<0.73 OE.
