Find the following z values for the standard normal variable Z. (You may find it useful to reference the z table. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)

a. P(Z ≤ z) = 0.9326
b. P(Z > z) = 0.7389
c. P(−z ≤ Z ≤ z) = 0.78
d. P(0 ≤ Z ≤ z) = 0.3082
