Question: A large college was interested in the salaries of graduates
A large college was interested in the salaries of graduates from its business and computer studies programs. The college randomly selected a number of graduates from each program, and then matched the graduates as closely as possible in terms of age, experience, achievement at school, and location. The college collected data on the annual salaries of the graduates. At the 2.5% significance level, is there evidence of a difference in salaries of computer studies and business graduates from this college?
