A corrections researcher was interested in gender differences in the likelihood of an arrestee making bail. She recorded the dollar amount in cases where a bail bond was set and recoded whether the defendant was able to get out of jail (make bail). Her data are shown below: Men Women $ Made Bail $ Made Bail 1000 yes 500 Yes 300 yes 250 no 1500 yes 250 no 200 yes 200 no 500 no 500 yes 150 yes 250 no 1000 no 100 no 500 yes 150 no 1200 yes 250 no Test the Null Hypothesis that there are no gender differences in dollar amounts for bail. Test the null hypothesis that the proportions of men and women who are released from jail does not differ. Use p=.05 to test the null hypothesis. For each test of the Null hypothesis report standard error of the difference between means or proportions, the obtained t, the degrees of freedom, and whether you accept or reject the null hypothesis.

- Test the Null Hypothesis that there are no gender differences in dollar amounts for bail.
- Test the null hypothesis that the proportions of men and women who are released from jail does not differ.
Use p=.05 to test the null hypothesis.
For each test of the Null hypothesis report standard error of the difference between means or proportions, the obtained t, the degrees of freedom, and whether you accept or reject the null hypothesis.
