Suppose a job-placement firm would like to know if the 2018 average starting salary for chemical engineering majors is higher than the 2018 average starting salary to electrical engineering majors. To conduct its test, the job-placement firm has selected a random sample of 110 chemical engineer majorsand 124 electrical engineering majorswho graduated and received jobs in 2018. The firm knows the standard deviation of salaries for chemical engineers is $7,700 and electrical engineers is $6,600.
