A study was conducted to see if the students living off campus had a grade point average which differed significantly from the university-wide average GPA of 2.65. Extensive records indicate that the standard deviation of GPA is 0.3. What is your conclusion, if a random sample of 100 off campus students had a mean GPA of 2.72? (The researcher feels that it is reasonable to assume that the population of GPA scores is normally distributed.) What is the significance probability of the observed result?
