The two dot plots below show the heights of some sixth graders and some seventh graders: Sixth Graders 52 53 54 55 56 57 Height (inches) Seventh Graders 52 53 54 55 56 57 Height (inches) The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 1.7. Approximately how many times the variability in the heights of the sixth graders is the variability in the heights of the seventh graders? (Round all values to the tenths place.)
