Using the same data set (Chapter 11 Data Set 1), test the research hypothesis at the .01 level of significance that there is a difference between boys and girls in the number of times they raise their hands in class. Do this practice problem by hand using a calculator. You use the same data for this problem as for Question 1, but you have a different hypothesis (one is directional and the other is non-directional). What is your conclusion regarding the research hypothesis? How do the results differ, and why?
