A business mаgаzine did а study tо determine hоw much mоre a supervisor makes than other employees. They sent a questionnaire to companies in the San Diego area and asked the average amount of money their supervisors make and the average amount their regular employee make. Our data is made up of the few companies that responded to the questionnaire. If we let population 1 represent supervisors monthly salary and population 2 represent regular employees monthly salary, we obtained a 95% confidence interval estimate of the difference (supervisors – regular) to be (+$457.18 , +$2160.37). Determine whether the following statements are true or false interpretations of this confidence interval. b. The confidence interval tells us that regular employees make an average of $457.18 and supervisors make an average of $2160.37.
