Answer 1

Answer:

a) z=0.845

b) z=1.185

c) z=-0.925

d) z=1.881

Step-by-step explanation:

The question is incomplete.

Given that is a standard normal random variable, find for each situation (to 2 or 3 decimals).

a. The area to the left of z is 0..8 .  z=0.845

b. The area to the left of z is 0.882 .  z=1.185

c. The area to the right of z is 0.8225 .  z=-0.925

d. The area between -z and z is 0.94.  z=1.881 (Hint: Enter the positive z-value)
