1. See “Content/Distribution Tables/Z table - 0 to Z” to answer
the following questions. The values of probability, or area from 0
to Z, for negative value of Z is the same as given for positive Z
by symmetry, i.e., the table values are for + and – values of Z.
Don’t forget the area of the left and right half of the normal
distribution is .5. See Normal Distribution & Z Values in
