Suppose an experiment is done with criminals released from prison in a certain state where the recidivism rate is 33%; that is, 33% of criminals return to prison within three years. One hundred random prisoners are made to attend a "boot camp" for two weeks before their release, and it is hoped that "boot camp" will have a good effect. Suppose 29 of those prisoners return to prison within three years. The null hypothesis is that those attending boot camp have a recidivism rate of 33%, p = 0.33. Complete parts (a) through (c) below. a. What is p, the sample proportion of successes? (It is somewhat odd to call returning to prison a success.) p= (Type an integer or a decimal. Do not round.) b. What is po, the hypothetical proportion of success under the null hypothesis? Po (Type an integer or a decimal. Do not round.) c. What is the value of the test statistic? Explain in context. z= (Round to two decimal places as needed.) The value of the test statistic tells that the observed proportion of prisoners was (Round to two decimal places as needed.) the null hypothesis proportion of prisoners.
