1. Describe the difference between sample and sampling distribution. Your response must be in complete sentences and you might use sketches to aid you.
2. You're interested in average number of months MSU graduates spend looking for jobs after the graduation as compared to RU students. You take random sample of MSU students and random sample of students from RU. The sample mean for MSU is 5.7 months and sample standard deviation is 2.1 months (N=100). The sample mean for RU is 2.5 months and sample standard deviation is the 1.1 months (N=100). Employ all of your hypothesis steps to test whether MSU students significantly differ from the RU students in average number of months they spend looking for job after graduation.
