Exercise

Boot Camp Suppose an experiment is done with criminals released from prison in a certain state where the recidivism rate is 40%; that is, 40% 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.

The null hypothesis is that those attending boot camp have a recidivism rate of 40%, p = 0.40. Report the alternative hypothesis in words and in symbols.
