Total in sample  = [ 1017 + 46 + 649 + 22 + 2715 + 319 + 919 + 73 ] =  5760   (1)

 

Total unemployed   =  [ 46 + 22 + 319 + 73 ]  =  460     (2)

 

% Unemployed   =   (2)   /(1)   =   460 / 5760   =  7.9%    (round to 8% ) ⇒  "B"

We have 46+22+319+73=460 people unemployed. In total, we have 1017+649+2715+919+460=5760 people. Thus, \(\frac{460}{5760}*100\approx8\) or (B).
