The United Nations has hired you as a consultant to help identify factors that predict manufacturing growth in developing countries. You have decided to use multiple regression to develop a model and identify important variables that predict growth. You have collected the data in the data file Developing Country from 48 countries. The variables included are percentage manufacturing growth (y), percentage agricultural growth (x1), percentage exports growth (x2), and percentage rate of inflation (x3) in 48 developing countries. Develop the multiple regression model and write a report on your findings.
