The management of Early Bloom, a large elementary school, is reevaluating its teachers’ salaries. They have hired a researcher to use regression analysis to predict teachers’ mean salaries at each elementary school in the city. The salary (Y) of a teacher is based on her/his years of experience (X). The resulting model is:

(a) If a teacher has 10 years of experience, what is her forecasted salary?

(b) If a teacher has 5 years of experience, what is his forecasted salary?

(c) Based on this equation, for every additional year of service, a teacher could expect his or her salary to increase by how much?
