The mean grade point average for one college is 2.45 with a standard deviation of 0.69. An engineering professor believes that the engineering majors have a higher GPA than the college's mean. A sample of 20 engineering majors had a mean GPA of 2.65. Test the professor's claim at the 0.01 level of significance. State the hypothesis. (again use u for population mean and write out null and alternate hypothesis) (For example: null hypothesis: u=123, alternate hypothesis u<123)
