Two college students, student A and student B, recorded approximately how much they spent on
food, in dollars, each day for 7 days.
The mean for student A's data set is $22.60, and the mean for student B's data set is $28.60. The
The MAD for student A's data set is about $1, and the MAD for student B's is $1.20.
Which statement best describes the two data sets in terms of means and mean absolute deviations
(MADS)?
O The difference is not meaningful because the means are separated by about 0.5 MADs.
O The difference is meaningful because the means are separated by about 3 MADs.
O The difference is meaningful because the means are separated by about 5 MADs.
O The difference is not meaningful because the means are separated by about 1 MAD.
