Darlene is a stunt motorcyclist in a traveling circus. For the climax of her show, she takes off from the ramp at angle _0, clears a ditch of width L, and lands on an elevated ramp (height h) on the other side (Figure 3-42). (a) For a given height h, find the minimum necessary takeoff speed vmin nee

Statistics: Informed Decisions Using Data 4
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
