Selecting 14 cases involving males convictingof trying hire someone to kill their wives and 16 cases of femalesconvicting of trying to hire to kill their husbands, thecriminologist finds the following:
Mean length of sentence for males =7.34 years with a standard deviation of 2.51 years.
Mean length of sentence of females =9.19 years with a standard deviation of 3.78 years.
Assume you are working at the .05 levelof significance.
