(b) An experiment to compare the spreading rates of five different brands of yellow interior latex paint available in a particular area used 4 gallons of each paint. The sample average spreading rates (ft2/gal) for the five brands were tabulated in Table 3. The computed value of F was found to be significant at level a-0.05. Given MSE-272.8 and n= 6. Table 3: Average spreading rates (ft²/gal) of paint for different brands Brand X1 x2 X3 X4 Xs Average spreading rates (ft²/gal) 5462.0 5512.8 5437.5 5469.3 5532.1 (i) Is there any significant difference in the true average spreading rates between brand X3 and X5? Use LSD procedure to support your answer. ii) Please identify which average spreading rate is greater between X3 and X5.
