1. CollegeBoard. com claims that college students have a mean of 60 college credits by the beginning of their third year. The registrar office at Nassau Community College believes this
claim is too low. A random sample of 100 students entering their third year of college has a
mean of 66 college credits with a standard deviation of 10 college credits. Do these results
support the professor's claim at <= 5%?
