Reference exercise 11

An experiment to compare the spreading rates of five different brands of yellow interior latex paint available in a particular area used 4 gallons (J = 4 ) of each paint. The sample average spreading rates for the five brands were , and . The computed value of F as found to be significant at level α = .05. With MSE = 272.8, use Tukey’s procedure to investigate significant differences in the true average spreading rates between brands.
