A scout group recorded jump-rope counts during a class activity for the challenge group. The same data is shown two ways. Line plot (each X = 1 data value): 47: X; 52: X; 54: X X X; 57: X X X X. Stem-and-leaf plot (key: stem 4 with leaf 7 means 47): Stem 4: leaves 7; Stem 5: leaves 2 4 4 4 7 7 7 7. Which statement can be verified from either display?
