Suppose an experiment is done with criminals released from prison in a certain state where the recidivism rate is 32%; that is, 32% 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 27 of those prisoners retum to prison within three years. The null hypothesis is that those attending boot camp have a recidivism rate of 32%, p = 0.32. 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 =0.32| (Type an integer or a decimal. Do not round.)
