Question

Given that z is a standard normal random variable, find z for each situation (to 2 decimals) a. The area to the right of z is 0.03. b. The area to the right of z is 0.045 c. The area to the right of z is 0.05 d. The area to the right of z is 0.1

Answer 1

solution:-
given that
a.the area to the right of z is 0.03
z = -1.88
b.the area to the right of z is 0.045
z = -1.70
c..the area to the right of z is 0.05
z = -1.64
d..the area to the right of z is 0.1
z = -1.28

The z values can be located from the area under the standard normal curve table.
