(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%.
