QUESTION #7

JSU has two separate campuses that are required to teach on - JSU Central City and JSU Sea City. After a few weeks, you discover that student attendance at Sea City campus is not as consistent for your class than on the Central City campus. Some days, the classrooms are full, but on other days, the seats feel empty. You wonder if the number of students on the Sea City campus is more variable than on the Central City campus. You collect the following data on the number of students in a one week of lectures on Sea City campus and on Central City campus:

JSU Central City: 156, 278, 134, 202, 236, 198, 187, 199, 143, 165, 223

JSU Sea City: 345, 332, 309, 367, 388, 312, 355, 363, 381

You decide to us a 5% significance level. You compute the sample variances and utilizes an F-test to determine if there has been a difference in variability
