Suppose an experiment is done with criminals released from prison in a certain state where the recidivism rate is 38%; 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 35 of those prisoners return to prison within three years. The null hypothesis is that those attending boot camp have a recidivism rate of 38%, p = 0.38. Complete parts (a) through (c) below. a. What is .3, the sample proportion of successes? (It is somewhat odd to call returning to prison a success.) B= E (Type an integer or a decimal. Do not round.) b. What is p0. the hypothetical proportion of success under the null hypothesis? pD = E (Type an integer or a decimal. Do not round.) 0. What is the value of the test statistic?
