Mike Jimenez is president of the teachers' union for Preston School District. In preparing for upcoming negotiations, he would like to investigate 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 rating of teaching effectiveness given by the principal, and whether the teacher has a master's degree (O = No, 1 = Yes). A random sample of 20 teachers resulted in the following data. Years of Experience Principal's Rating 96 52 75 80 62 Salary ($ Thousands) Master's Degree 51.1 8 43.6 39.3 53 48.6 55 52 46.8 58.6 41.7 35.7 40.6 61.8 46.7 2 15 1 11 14 68 1 94 64 54 57 66 63 92 64 88 7 1 22 1 1 1 23 17 12 48.4 43.6 51.8 40.7 14 57 63 1 74 78 70 42.8 42.9 Click here for the Excel Data File.
