6.) Find the z-score such that the area under the standard normal curve to its left is 0.01

7.) Find the z-score such that the area under the standard normal curve to its right is 0.15.

8.Find the z-scores that separate the middle 85% of the distribution from the area in the tails of the standard normal distribution.
