Question

Find the point zz with 64%64% of the observations falling below it. Enter your answer rounded to two decimal places.

Find the point zz with 25%25% of the observations falling above it. Enter your answer rounded to two decimal places.

Answer 1

Answer #1

Solution :

Given that,

Using standard normal table ,

A.

P(Z < z) = 64%

P(Z < 0.36) = 0.64

z = 0.36

B.

P(Z > z) = 25%

1 - P(Z < z) = 0.25

P(Z < z) = 1 - 0.25

P(Z < 0.67) = 0.75

z = 0.67
