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.

Answer:
Choice D is correct answer.
Step-by-step explanation:
We have to find an integer multiple of unit fraction 1/4.
3 is an integer.
