6) A student has to decide whether he wants to major in electrical engineering or computer
science. To find out which job pays more, he interviews eight alumni in each profession and asks
them what their starting salary was. The electrical engineering alumni had a mean starting salary
of $54,000 and a standard deviation of $10,000. The computer science alumni had a mean
starting salary of $62,000 and a standard deviation of $8,000. It is reasonable to assume equal
population variances, and assume starting salaries are normally distributed. Make a conclusion
at the 5% significance level to determine if electrical engineering and computer science majors
mean starting salaries are equal. Follow the 5-step process.
