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.

I. Solve the following problems involving Test of Difference of Means. Show your full solution including hypotheses
and conclusion.
1. 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:
Conventional Method
Use of Computers
Sample Mean
Sample Standard Deviation
Sample Size
H = 84
S, = 8
H2= 92
Sz = 5
n = 15
n2 = 10
