The recidivism rate for convicted sex offenders is 16%. A warden suspects that this percent is higher if the sex offender is also a drug addict. Of the 304 convicted sex offenders who were also drug addicts, 55 of them became repeat offenders. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: ? - Select an answer (please enter a decimal) H1: ? v Select an answer v |(Please enter a decimal) c. The test statistic ? v (please show your answer to 3 decimal places.)

Question
The recidivism rate for convicted sex offenders is 16%. A warden suspects that this percent is higher if the sex offender is also a drug addict. Of the 304 convicted sex offenders who were also drug addicts, 55 of them became repeat offenders. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Но: ? v Select an answer (please enter a decimal) H1: ? v Select an answer ♥ (Please enter a decimal) c. The test statistic ? 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 ? v f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the populaton proportion is significantly higher than 16% at a = 0.10, so there is statistically significant evidence to conclude that the population proportion of convicted sex offender drug addicts who become repeat offenders is higher than 16%. The data suggest the population proportion is not significantly higher than 16% at a = there is statistically significant evidence to conclude that the population proportion of convicted sex offender drug addicts who become repeat offenders is equal to 16%. 0.10, so The data suggest the population proportion is not significantly higher than 16% at a = 0.10, so there is statistically insignificant evidence to conclude that the population proportion of convicted sex offender drug addicts who become repeat offenders is higher than 16%. h. Interpret the p-value in the context of the study. There is a 15.99% chance that more than 16% of all convicted sex offender drug addicts become repeat offenders. If the sample proportion of convicted sex offender drug addicts who become repeat offenders is 18% and if another 304 convicted sex offender drug addicts are observed then there would be a 15.99% chance of concluding that more than 16% of all convicted sex offender drug addicts become repeat offenders. There is a 15.99% chance of a Type I error. If the population proportion of convicted sex offender drug addicts who become repeat offenders is 16% and if another 304 convicted sex offender drug addicts are surveyed then there would be a 15.99% chance that more than 18% of the 304 convicted sex offender drug addicts in the stuudy will become repeat offenders
