Using Table 4A and the symmetry property of the normal distribution, complete the following charts of z-scores. The area given in the tables is the area to the right under the normal distribution in the figures.
a. z-scores associated with the right-hand tail: Given the area A, find z(A).

b. z-scores associated with the left-hand tail: Given the area B, find z(B).
