Find the following z values for the standard normal
variable Z. Use Table 1. (Negative
values should be indicated by a minus
sign. Round your answers to 2 decimal places.)
a.
P(Z ≤ z) = 0.1105
b.
P(z ≤ Z ≤ 0) = 0.1607
c.
P(Z > z ) = 0.7698
d.
P(0.25
≤ Z ≤ z) = 0.3428

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
