Faulkner University typically offers evening classes that should run from 6:00 p.m. to 9:30 p.m. The university-wide average for evening class length, though, is 135 minutes, considerably less than what is expected. The standard deviation for the entire university is 15 minutes. The Birmingham campus of Faulkner University has 144 students, and they feel like they are meeting longer than the average class. Indeed, they are: the typical class length for the Birmingham campus is 160 minutes. Here's the question: Is the longer class length for the Birmingham students significantly different than the overall campus? For it to be significantly higher than average, it must be higher than 95% of the population. Prove whether the students are meeting significantly longer than the rest of the university.
