Question

A statistics teacher teaches his subject in a conventional way. However, he began to teach Statistics with computer using statistics software in a second class. He gave an examination at the end of the quarter to both class and has observed that the students taught with computers tend to have higher scores than those taught using conventional way. The teacher decides to test the hypothesis, at 1% level of significance, that the students who are taught statistics with computers learn better than those taught using the conventional way. The data gathered is as follows:
