A job-placement firm would like to know if the average starting salary in a particular year for chemical engineering majors is higher than the average starting salary in that same year for electrical engineering majors. To conduct its test, the job-placement firm has selected a random sample of 124 electrical engineering majors and 110 chemical engineering majors who graduated and received jobs in that year. Each graduate was asked to report his or her starting salary. The results of the survey are below. Complete parts a and b. Click the icon for the results of the survey. a. Conduct a hypothesis test at the 0.10 level of significance to determine whether the mean starting salary for chemical engineering graduates was higher than the mean starting salary for electrical engineering graduates. Assume the populations from which the samples were taken are approximately normally distributed with equal variances. Let my be the population mean starting salary for chemical engineering graduates, and 2 be the population mean starting salary for electrical engineering students. State the null and alternative hypotheses. OA. HO: H1 - H250 OB. HO: H1 - H2= 0 HA: 1 1 - 12 >0 HA : H1 - 12 # 0 OC. HO: H1 - H2
