Many people believe that criminals who plead guilty tend to get lighter sentences than those who are convicted in trials. The accompanying table summarizes randomly selected sample data for defendants in burglary cases. All of the subjects had prior prison sentences. Use a 0.05 significance level to test the claim that the sentence (sent to prison or not sent toprison) is independent of the plea. If you were an attorney defending a guilty defendant, would these results suggest that you should encourage a guilty plea? a. Determine the test statistic. chi squared equals (Round to three decimal places as needed.) b. Determine the P-value of the test statistic. P-value equals (Round to four decimal places as needed.)
