The data file Economic Activity contains data for the 50 states in the United States; the variables are described in the Chapter 11 appendix. You are asked to develop a model to predict the percentage of females that are in the labor force. The possible predictor variables are per capita disposable personal income, the percentage of males unemployed, the manufacturing payroll per worker, and the unemployment rate of women (x3). Compute the multiple regression and write a report on your findings.
