6. -/13 POINTS DEVORESTATS 10.8.011. MY NOTES An experiment to compare the spreading rates of five different brands of yellow interior latex paint available in a particular area used 4 gallons () - 4) of each paint. The sample average spreading rates (ft/gal) for the five brands were 1. - 462.0, X2-512.8, X3. - 437.5,4 = 469.3, and s. - 532.1. The computed value of F was found to be significant at level a = 0.05. With MSE - 380.8, use Tukey's procedure to investigate significant differences between brands. (Round your answer to two decimal places.) Which means differ significantly from one another? (Select all that apply.). X and X2 X and X3 Ox, and X and X X and X3 X and X4 Ox, and is X and X 23 and X and X There are no significant differences You may need to use the appropriate table in the Appendix of Tables to answer this question.
