Answer 1

What z score in a normal distribution has 33% of all score above it?

Answer: A z score which has 33% of all scores above it, will have 67% of all scores  below it.

To find the required z score, we need to find the z value corresponding to probability 0.67.

Using the standard normal table, we have:

$z(0.67)=0.44$

Therefore, the z score = 0.44 has 33% of all score above it.
