you set the mean to 25 and the standard deviation to 5.
for between 22 and 29, greater than 29, less than 22, you select area from a value.
for bottom 5% and top 5%, you select value from an area.


you can do the same thing with z-scores, but this calculator allows you to work directly from the mean and the standard deviation.


if you need to now how to work with z-scores, let me know and i'll guide you through that.
