Hi!
To find the Mean Absolute Deviation (MAD) of the weight of the boxes, first find the mean.
5 + 3 + 3 + 4 + 5 + 4 = 24
24/6 = 4
Now find the absolute distance from the mean for each of the numbers by subtracting the mean from each of the numbers. It doesn't matter if it's negative.
5 - 4 = 1
3 - 4 = 1
3 - 4 = 1
4 - 4 = 0
5 - 4 = 1
4 - 4 = 0
Now find the mean of those numbers.
1 + 1 + 1 + 0 + 1 + 0 = 4
4/6 = 0.7
So now we know the answer is either B or D.
B. 0.7 pound; the weight of 50% of the boxes is greater than 0.7 pound
D. 0.7 pound; on average, the weight of a box varies 0.7 pound from the mean of 4 pounds
The answer is D. Let me know if you don't understand that.
Hope this helps! :)

Answer:
0.7 pound; on average, the weight of a box varies 0.7 pound from the mean of 4 pounds
Step-by-step explanation:
The mean is 4 since adding everything up makes 24 and dividing that by the 6 boxes is 4, subtracting everything by 4 (ignoring if its negative) adds up to 0.7
