How does the mean absolute deviation (MAD) of the data in set 1 compare to the mean absolute deviation of the data in set 2? Set 1: 12, 8, 10, 50

Set 2: 13, 9, 8

choices:
A: The MAD of set 1 is 13 less than the MAD of set 2.
B: The MAD of set 1 is 13 more than the MAD of set 2.
C: The MAD of set 1 is 2 more than the MAD of set 2.
D: The MAD of set 1 is 2 less than the MAD of set 2.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
