Answer 2

D:

Answer 3

find the mean
(30+30+35+35+40) / 5 = 170/5 = 34
now take the absolute value of the difference from each set of data
| 30 - 34 | = | -4 | = 4
|30 - 34| = | -4| = 4
| 35 - 34| = 1
| 35 - 34| = 1
| 40 - 34| = 6
now take the mean (average) of these numbers
(4 + 4 + 1 + 1 + 6) / 5
16/5 = 3.2 <=== this is you MAD (mean absolute deviation)
