Problem 1: test the research hypothesis at the .05 level of significance that boys raise their hands in class more often than girls.
What is your conclusion regarding the research hypothesis? Remember to first decide whether this is a one or two tailed test.
Problem 2: 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.
What is your conclusion regarding the research hypothesis? You used the same data for this problem as for question 1, but you have a different hypothesis (one is directional and the other is nondirectional). How does the results differ and why?
