Solution:
Given that,
Using standard normal table
z = - 1.2804
Using standard normal table
z = 0.3081
c ) P ( Z > z ) = 0.8204
= 1 - P ( Z < z ) = 0.8204
Using standard normal table
P ( Z < z ) = 1 - 0.8204
P ( Z < z ) = 0.1796
z = - 0.91689
P ( Z z ) - P (
Z
0.36 ) =
0.3458
Using standard normal table
z = 2.2086
