The recidivism rate for convicted sex offenders is 15%. A warden suspects that this percent is lower if the sex offender is also a drug addict. Of the 372 convicted sex offenders who were also drug- addicts, 41 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: ?v Select en enswer v (please enter a decimal). Hzv Select an answer v (Please enter a đecimal). 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 ?va f. Based on this, we should Setect an answer-v-i the null hypothesis. g. Thus, the final conclusion is that: O The data suggest the populaton proportion is significantly lower than 15% ata=0:01, 5o there is statistically significant evidence to conclude that the population proportion f cdevicted sex offender drug addicts who become repeat offenders is lower than 15%. The data suggest the population proportion is not significantly lower than 15% 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 lawer than 15%.

Question
Transcribed Image Text:The recidivism rate for convicted sex offenders is 15%. A warden suspects that this percentis lower
if the sex offender is also a drug addict. Of the 372 convicted sex offenders who were also drug
addicts, 41 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: ? v Select an enswer ♥
(please enter a decimal)
(Please enter a decimal)
H?v Select an answer ♥
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 ?vQ
f. Based on this, we should Setect an answer v the null hypothesis.
g. Thus, the final conclusion is that.
O The data suggest the populaton proportion is significantly lower than 15% at a = 0.01,
so there is statistically significant evidence to condude that the population pFoportion of
cclevicted sex offender drug addicts who become repeat offenders is ower than 15%.
O The data suggest the population proportion is not significantly lower than 15% 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
lower than 5%.
