The recidivism rate for convicted sex offenders is 13%. A warden suspects that this percent is lower if the sex offender is also a drug addict. Of the 348 convicted sex offenders who were also drug addicts, 31 of them became repeat offenders. What can be concluded at the ax = 0.01 level of significance? a.

The recidivism rate for convicted sex offenders is 13%. A warden suspects that this percent is lower if the sex offender is also a drug addict. Of the 348 convicted sex offenders who were also drug addicts, 31 of them became repeat offenders. What can be concluded at the a= 0.01 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 ... = (please enter a decimal) (Please enter a decimal) (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) Select an answer the null hypothesis. O The data suggest the population proportion is not significantly lower than 13% 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 13%. The data suggest the populaton proportion is significantly lower than 13% 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 lower than 13%. O The data suggest the population proportion is not significantly lower than 13% at c = 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 lower than 13%. h. Interpret the p-value in the context of the study. O There is a 1.16% chance that fewer than 13% of all convicted sex offender drug addicts become repeat offenders. There is a 13% chance of a Type I error. O If the population proportion of convicted sex offender drug addicts who become repeat offenders is 13% and if another 348 inner city residents are surveyed then there would be a 1.16% chance that fewer than 9% of the 348 convicted sex offender drug addicts in the study become repeat offenders. O If the sample proportion of convicted sex offender drug addicts who become repeat offenders is 9% and if another 348 convicted sex offender drug addicts are surveyed then there would be a 1.16% chance of concluding that fewer than 13% of convicted sex offender drug addicts become repeat offenders. 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 lower than 13% and if another 348 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 13%. O If the population proportion of convicted sex offender drug addicts who become repeat offenders is 13% and if another 348 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 lower than 13%. O There is a 1% chance that Lizard People aka "Reptilians" are running the world. There is a 1% chance that the proportion of all convicted sex offender drug addicts who become repeat offenders is lower than 13%.
