Oxnard Petro, Limited, has three interdisciplinary project development teams that function on an ongoing basis. Team members rotate from time to time. Every 4 months (three times a year) each department head rates the performance of each project team (using a 0 to 100 scale, where 100 is the best rating). Are the main effects significant? Is there an interaction?

O The main effects of department and year are significant, but there is not a significant interaction effect. The main effect of department is significant; however, there is no significant effect from year or interaction between department and year. The main effect of year is significant; however, there is no significant effect from department or interaction between department and year. (d) Interpret the p-values carefully
