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 th accompanying table. A logger working on the road claims that the mean skidding distance is at least 425 meters. Is there sufficient evidence to refute this claim? Use a = 0.10. E Click the icon to view the table. State the hypotheses to test if there is sufficient evidence to refute the claim that the mean skidding distance is at least 425 meters.
