The major that you choose in college can have an impact on your future in terms of income and quality of life. Some majors, such as petroleum engineering and pharmaceutical sciences, make more on average than other majors. A random sample of 22 petroleum engineering and pharmaceutical sciences graduates have a mean annual salary of $54,118 with a standard deviation of $1479. Given that the distribution is approximately normal, test the hypothesis that the mean annual salary for petroleum engineering and pharmaceutical sciences graduates is $53,000. What is the critical value(s) for this test?
