Question

FIND THE Z-SCORE FOR WHICH THE AREA TO THE RIGHT IS 0.52.

A)0.13

B)-0,05

C)-0.12

D)-0.26

Answer 1

Using standard normal z-table we, want to find the z-score for which the area to the right is 0.52.

That is to find, z-score such that, P(Z > z) = 0.52

P(Z > z) = 0.52

=> 1 - P(Z < z) = 0.52

=> P(Z < z) = 1 - 0.52

=> P(Z < z) = 0.48

Using z-table we get, z-score corresponding probability of 0.48 is, z = -0.05

=> P(Z > -0.05) = 0.52

Answer : B) -0.05
