# Question: Using the normal table in the back of the book

Using the normal table in the back of the book or software, find the value of z that makes the following probabilities true. You might find it helpful to draw a picture to check your answers.

(a) P (Z < z) = 0.20

(b) P (Z ≤ z) = 0.50

(c) P (-z ≤ Z ≤ z) = 0.50

(d) P (∣Z∣< z) = 0.01

(e) P (∣Z∣ > z) = 0.90

(a) P (Z < z) = 0.20

(b) P (Z ≤ z) = 0.50

(c) P (-z ≤ Z ≤ z) = 0.50

(d) P (∣Z∣< z) = 0.01

(e) P (∣Z∣ > z) = 0.90
