We calculate BSS = 10 * (540.3 - 543.6)2 + 16 * (602.9 - 543.6)2 + 17 * (489.8 - 543.6)2 = 105578.2 WSS = (10 - 1) * 46.42 + (16 - 1) * 47.42 + (17 - 1) * 48.92 = 91337.4 F = (BSS / (k-1)) / (WSS / (n-k)) = (105578.2 / (3 - 1)) / (91337.4 / (43 - 3)) = 23.1 The critical F value is F.05,2,40 = 3.23. The observed value vastly exceeds this, so we clearly reject the null hypothesis and conclude that the means differ across the groups.
