What Z value corresponds to the lowest 20% under a normal curve

First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the Z score related to that proportion. Remember that Zs below the mean are negative.
