Draw approximated normal distribution based on mean, median, percentiles?

Hello all,

I searched the forum for any info on this, so here goes.

I need to reference some statistical data from a study. The information
given there for an age distribution is: mean, standard deviation,
median plus the 25th and 75th percentiles. Now, I have tried in vain to
get Excel or SPSS to draw this for me. Is there any way of inputting
percentiles and median into Mathematica? The normal distribution
function only takes mean and sd as far as I know.


Any help would be much appreciated.
Richard
