We conduct a study to assess if there is the same variation in grades between engineering students and psychology students, who are all graded on a scale of grades between 0 and 100. We sample 15 psychology students that have a standard deviation of 36 points in their grades. 15 engineering students are also sampled and have a standard deviation of 19 points in their grade. We want to know if the population variations are different at the 1% significance level. Determine the hypothesis then run the test using a critical value approach. Do not forget to interpret your results.
