A review session is given in order to find if the group who attends it has a better average than who doesn't. The grades are organized into two independent groups and the data is obtained. The mean and standard deviation of the 29 students who attended the review session are 70.5 and 11.6 percent respectively. The mean and standard deviation of the 14 students who did NOT attend the review session are 64.6 and 16.1 percent respectively. In this problem,...
