Question

What is the `Z`-score value that separates the top `70%` of a normal distribution from the bottom `30%`?

Answer 1

`-0.5244`

Explanation:

For finding Z score value that seperates the top 70% of a normal distribution from the bottom 30%, one needs to identify the point to the left of which we have an area of `30%`I and `70%` to the right of it or `20%` between it and the mean value.

One can look for tables for this and it should be `-0.5244`
