The true value of one type of degree or diploma cannot be quantitatively measured, but we can measure its relative impact on starting salary. Graduates from Quebec universities with a B.A. or a B.Sc. degree have a mean annual starting salary of $28,300. Sixty-five Quebec graduates with a civil engineering degree are randomly selected. Their starting salaries have a mean of $36,300 (based on "Annual Salary Survey," Peat Marwick Stevenson & Kellogg). If the standard deviation is $1670, use a 0.01 level of significance to test the claim that Quebec graduates with a civil engineering degree have a mean starting salary that is greater than the mean for graduates with a B.A. or B.Sc. degree from Quebec. Is the sample size large enough to reach a conclusion?
