Basic Math

An experiment to compare the spreading rates of five differentbrands of yellow interior latex paint available in a particulararea used 4 gallons (J = 4) of each paint. The sampleaverage spreading rates (ft2/gal) for the five brandswere x1. = 462.0, x2. =512.8, x3. = 437.5, x4. =469.3, and x5. = 532.1. The computed value ofF was found to be significant at level ? = 0.05.With MSE = 480.8, use Tukey's procedure to investigate significantdifferences between brands. (Round your answer to two decimalplaces.)
w =

pooled standard deviation                                                                             =Sp =?MSE      = 21.93
critical value of q with 0.05 level and at k=5 and N-k=15 degree of freedom= 4.37
Tukey's (HSD) for group i and j =w= (q/?2)*(sp*?(1/ni+1/nj)         = 47.91
x1-x2 50.80 significant difference
x1-x5 70.10 significant difference
x2-x3 75.30 significant difference
x3-x5 94.60 significant difference
x4-x5 62.80 significant difference
