You need to look for the area to the left of the z-score from the table. 
i found a z-score of.84 yielded .7995 area to the left of that z-score and i found a z-score of .85 yielded .8024 area to the left of that z-score. 
0.7995 is much closer to 0.80 than 0.8024, so the z-score chosen as the solution is a z-score of .84. 
the z-score of .84 is an addition of 0.8 in column 1 with .04 in column 7 
 
it's the intersection of the area in the row of .8 with the column of .04. 
this is shown in the following picture.

PE=PA^2/PA=6^2/4=9
BE=PB-PE=9-4=5
