see the second applet: Choose parameters and the cut-off points will be calculated. choose a mean of zero, and shaded area .0827, below.
You will be given by that button the standard deviations. So if you know that and the standard deviation, you can multiply to get the mean. http://davidmlane.com/hyperstat/z_table.html
In a given normal distribution, the standard deviation is 14.4 and 8.27% of the distribution lies to the left of 60. What is the mean?
