Exercise 3. Solve the following problems. 1. A mathematics teacher wants to study if the modular approach of leaning affects the performance of the students in an examination. From the previous examination, it was noted that the population mean for an examination is 44 with a standard deviation of 4. The teacher then applied the modular approach of learning to a sample of 20 students and after the examination, a sample mean of 46 is calculated. Can the teacher claim that the modular approach is effective in improving the performance of the students in an examination? Use g=0.05.
