When planning for a new forest road to be used for tree harvesting, planners must select the location to minimize tractor skidding distance. The skiding distances ( in meters) were measured at 20 randomly selected road sites. The sample results were x= 357.5, s= 117.29. Logger working on the road claims the skidding distance is at least 400 meters. Is there sufficient evidence to refute this claim?
