A city council suspects a judge of being a "hanging judge"because s/he is perceived as imposing harsher penalties for thesame sentence. To investigate this, a random sample of 45 cases istaken from the judge's prior cases that resulted in a guiltyverdict for a certain crime. The average jail sentence s/he imposedfor the sample is 25 months. The average jail sentence for the sametype of crimes is 23 months with a standard deviation of 13 months.What can be concluded with ? = 0.01?
What is the appropriate test statistic?
