Estimate: Wage 60 + 61 Educ +62 Exper + 63Age + 64 Male + E. Note: Negative values should be indicated by a minus sign. Round your answers to 2 decimal places. Wage = Hint References Educ + Exper+ Age+ Male b. Predict the hourly wage of a 45-year-old male and female employee with 8 years of higher education and 8 years of experience.
