A recent study investigated tractor skidding distances along a road in a forest. The skidding distances (in meters) were measured at 20 randomly selected road sites. The data are given in the accompanying table. A logger working on the road claims that the mean skidding distance is at least 425425 meters. Is there sufficient evidence to refute this claim? Use alphaαequals=0.050.05.
