Homeworks chapter 6 6.5 a) According to the above results, the p value of the interaction effect is zero. So the interaction effect is significant at 0.05 level. Therefore there is sufficient evidence to claim that the vibration rate is affected by the interaction of both bit size and cutting speed. b)

Also in the residuals Vs. fitted plot there is no any pattern observed. So there is no serious violations in the constant variance assumption too. So the model assumptions are satisfied. c) 2 1 40 30 20 2 1 40 30 20 A B 1 2 A 1 2 B Interaction Plot for response Data Means According to the above interaction plot, the vibration level is low when the bit size is at lower level.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
