What is the mean of the values in the tail of a normal distribution?

[Stan Hilliard]

I would like to know how to determine the mean of the values in the tail of a normal distribution -- if I know the mean & SD and z of the tail?  One would think there would be a table of that. A close estimate might be to treat the observations as if they all had the value that divides the tail from the rest of the distribution.

I don't understand your question, but it doesn't sound related to power and sample size, so I suggest you seek a different forum for it.
