Explanation:

Data provided in the question:

Sales for the last four months :

8, 10, 15, and 9 units

Last four forecast of sales:

9, 11, 8 and 12 units

Now,

The mean absolute deviation (MAD) value of these forecast will be calculated as:

MAD = [ ∑|Sales - Forecast sales| ] ÷ [ Total number of forecast ]

or

MAD =  [ |8 - 9| + |10 - 11| + |15 - 8| + |9 - 12| ] ÷ 4

or

MAD = [ 1 + 1 + 7 + 3 ] ÷ 4

or

MAD = 12 ÷ 4

or

MAD = 3

the answer is: c.that person might be arrested and deported

filling w-4 form incorrectly usually would rise suspicions from government's auditors. when they notice such mistakes, they would send their teams to investigate the situation further.

if those investigation teams believe that the incorrectness is done on purpose (with malicious intent), that person can be arrested or deported
