Mean entrylevel salaries for college graduates with mechanical engineering degrees and electrical engineering degrees are believed to be approximately the same. A recruiting office thinks that the mean mechanical engineering salary is actually lower than the mean electrical engineering salary. The recruiting office randomly surveys 50 entry level mechanical engineers and 60 entry level elecuical engineers. Their mean salaries were $46,l00 and $45,700, respectively. Their standard deviations were $3,450 and $4,? 10, respectively. Conduct a hypothesis test to determine if you agree that the mean entrylevel mechanical engineering salary is lower than the mean entrylevel electrical engineering salary. You will need to present the answer in the format that shows all the steps of hypothesis testing For example: Given? Step1: what is the parameter of interest? Provide notation. 'What is the hypothesis of interest? Step2: W'hat method would you use to test the above hypothesis (stating the name of the function used in TIcalculator will suffice)? Provide brief reasoning for your choice. Step3: If using the pvaluemethod, then provide the name and value of the test statistic. If using the CImethod, then provide the name for the type of interval and its value. Step4: What do you conclude? Provide reasoning for your conclusion. ~l~li~lw~lu~ld
