The recidivism rate for convicted sex offenders is 11%. A warden suspects that this percent is higher if the sex offender is also a drug addict. Of the 332 convicted sex offenders who were also drug addicts, 50 of them became repeat offenders. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use z-test for a population proportion b. The null and alternative hypotheses would be: Ho: pv = (please enter a decimal) H₁: p= (Please enter a decimal) c.

Question
Question Z The recidivism rate for convicted sex offenders is 11%. A warden suspects that this percent is higher if the sex offender is also a drug addict. Of the 332 convicted sex offenders who were also drug addicts, 50 of them became repeat offenders. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use [z-test for a population proportion b. The null and alternative hypotheses would be: Ho: pv = H₁: pv = (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) c. The test statistic z = d. The p-value = e. The p-value is va f. Based on this, we should [Select an answer the null hypothesis. g. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) O The data suggest the population proportion is not significantly higher than 11% at a = 0.01, so there is statistically significant evidence to conclude that the population proportion of convicted sex offender drug addicts who become repeat offenders is equal to 11%. O The data suggest the population proportion is not significantly higher than 11% at a = 0.01, 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 11%. O The data suggest the populaton proportion is significantly higher than 11% at a = 0.01, 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 11%. h. Interpret the p-value in the context of the study. O There is a 0.9% chance that more than 11% of all convicted sex offender drug addicts become repeat offenders. There is a 0.9% chance of a Type I error. O If the sample proportion of convicted sex offender drug addicts who become repeat offenders is 15% and if another 332 convicted sex offender drug addicts are observed then there would be a 0.9% chance of concluding that more than 11% of all convicted sex offender drug addicts become repeat offenders. O If the population proportion of convicted sex offender drug addicts who become repeat offenders is 11% and if another 332 convicted sex offender drug addicts are surveyed then there would be a 0.9% chance that more than 15% of the 332 convicted sex offender drug addicts in the study will become repeat offenders. i.

i. Interpret the level of significance in the context of the study. O If the population proportion of convicted sex offender drug addicts who become repeat offenders is higher than 11% and if another 332 convicted sex offender drug addicts are observed then there would be a 1% chance that we would end up falsely concluding that the proportion of all convicted sex offender drug addicts who become repeat offenders is equal to 11%. O If the population proportion of convicted sex offender drug addicts who become repeat offenders is 11% and if another 332 convicted sex offender drug addicts are observed, then there would be a 1% chance that we would end up falsely concluding that the proportion of all convicted sex offender drug addicts who become repeat offenders is higher than 11%. O There is a 1% chance that the proportion of all convicted sex offender drug addicts who become repeat offenders is higher than 11%. O There is a 1% chance that Lizard People aka "Reptilians" are running the world.
