Suppose there is sufficient evidence to reject H0: m1 = m2 = m3 = m4 using a one-way ANOVA. The mean square error from ANOVA is determined to be 26.2. The sample means are x1 = 42.6, x2 = 49.1, x3 = 46.8, x4 = 63.7, with n1 = n2 = n3 = n4 = 6. Use Tukeys test to determine which pairwise means are sig

Thump-Thump Data Cities lay cables (plastic-coated sensors) in roadways to gather data on traffi c volume and speeds, causing a thump-thump sound. Based on thump-thump data, you have concluded that at a volume ( V ) of 1,500 vehicles, the time required for a 10-mile trip is 24 minutes, compared to 23
