R Squared = .709 (Adjusted R Squared = .553) R 2 = 0.709 (adjusted R 2 = 0.553). Looking at the treatment p-value = 0.48 < = 0.10, So I reject the H 0 .: that all treatments /machines are equivalent. To determine which machines are different, I used the Tukey multiple comparison test. Shown in the table below 5
S.FLORES Extra credit: The CI for operator 1 and operator 5, operator 1 and operator 6, operator 2 and operator 5, operator 2 and operator 6, and operator 3 and operator 5 do not contain 0, which means that I am 90% confident that the times differ for operators 1 & 5, 1 & 6, 2 & 5, 2& 6 and 3& 5. Because the intervals are strictly negative, I conclude that the times for operators 1 and 2 are shorter than operators 5 and 6, and the times for operator 3 are shorter than for operator 5. 6

### What students are saying

• 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.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• 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.
