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

Select an answer the null hypothesis.
O The data suggest the population proportion is not significantly higher than 15% at a = 0.05, 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 15%.
O The data suggest the populaton proportion is significantly higher than 15% at a = 0.05, 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 15%.
O The data suggest the population proportion is not significantly higher than 15% at a = 0.05, so
there is statistically significant evidence to conclude that the population proportion of
