Question 1186481: The z-score z that separates the highest 10% of all values of a standard normal random variable from the rest has which property?
- P(Z ≤ z)=0.10

- P(Z ≤ z)=0.90

- z=P(Z ≥ 0.90)

- z=P(Z ≤ 0.90)

The answer should be the 90th percentile of the standard normal distribution, hence it would have the property P(Z ≤ z) = 0.90.
