Answer: To determine the estimated multiple linear regression equation, we would need a dataset with observations for annual income, number of years of school completed, length of tenure in current employment, and age. With that data, we can perform a multiple linear regression analysis to estimate the equation.
The general form of a multiple linear regression equation is:
Income = β₀ + β₁ * Education + β₂ * Tenure + β₃ * Age + ε
In this equation:
Income represents the predicted annual income.
Education represents the number of years of school completed.
Tenure represents the length of tenure in current employment.
Age represents the age of the individual.
β₀, β₁, β₂, and β₃ are the coefficients that will be estimated through the regression analysis.
ε represents the error term.
