A professor in the ISE department claims that there is much more variability in the final exam scores of students taking the introductory statistic course as a requirement than for students taking the course as part of a major in Industrial Engineering (IE). Random samples of 13 non-IE majors (Group 1) and 10 IE majors (Group 2) are taken from the professor's class roster in his large lecture, and the results of the final exam scores show that the variances are 210.2 and 36.5, respectively. Do these data provide sufficient evidence to infer that there are differences in final exam scores between the two groups of students? Carry out an appropriate test of hypotheses at significance level 0.05 Answer in 4 decimals Please include your calculations - H0 - H1 - Test Statistic - Value of Test Statistic - What is the numerical value of the critical region? Upper:________, Lower:_________ - What is the p-value? - Decision (Reject or Failed to reject) - Conclusion
