Mike Wilde is president of the teachers' union for Ostego School District. In preparing for upcoming negotiations, he is investigating the salary structure of classroom teachers in the district. He believes there are three factors that affect a teacher's salary: years of experience, a teaching effectiveness rating given by the principal, and whether the teacher has a master's degree. A random sample of 20 teachers resulted in the following data. What is the value of the intercept given by a regression analysis on Excel? Answer to two places after the decimal. Years of Experience Principal's Rating Master's Degree Salary ($ thousands) 12 45 0 51.2 6 53 0 53.9 2 60 1 49.4 3 72 0 50.2 10 70 1 52.5 11 82 0 62.7 (A value of 1 indicates "yes", while a value of 0 indicates "no".)
