Refer to the Environmental Geology (Vol. 58, 2009) simulation study of how far a block from a collapsing rockwall will bounce down a soil slope, Recall that the variable of interest was rebound length (measured in meters) of the falling block. Based on the depth, location, and angle of block-soil impact marks left on the slope from an actual rockfall, the 13 rebound lengths shown in the table were estimated. (These data are saved in the ROCKFALL file.) Consider the fol lowing statement: "In all similar rockfalls, half of the rebound lengths will exceed 10 meters." Is this statement supported by the sample data? Test using a = .10.
