The formula of Mean Absolute Deviation is:

MAD = ∑|x- x̄|
            ----------     
                 n

Where:
x = data value
<span>x̄ = mean
</span>n = number of observations

You already have 2 values given which is the mean (7) and the number of observations (10). First you need to solve for the sum of x - <span> x̄. Let's put that in a table to get a better picture:

x             <span>|x-</span></span>x̄|
<span>4        |4-7| =   3
4</span>        |4-7| =   3<span>
6</span>        |6-7| =   1<span>
6</span>        |6-7| =   1<span>
7</span>        |7-7| =   0<span>
8</span>        |8-7| =   1<span>
8</span>        |8-7| =   1<span>
8</span>        |8-7| =   1<span>
9</span>        |9-7| =   2<span>
10</span>      |10-7| = 3

Now get the sum of the values in the column |x-x̄|. 
3+3+1+1+0+1+1+1+2+3 = 16

Now that you have the sum you can input it into the first formula:
MAD = ∑|x- x̄|
            ----------      
                 n
MAD =     16
            ----------      
                 10

MAD = 1.6

The answer is then B.
