Extracted text: A course in Statistics is taught to 60 students using the lecture method while a second group of the same number of the students taught the same course using modules. The mean score of the first group is 84.7 with a standard deviation of 5.2 while the second group mean is 83.55 with a standard deviation of 8.9. Test the hypothesis that using lecture method in teaching gives better results than using modules at 10% significant level (CV = 1.28)
