Normal distribution over time

[GeoTrek]

Hi all,

I am attempting to create a normal distribution. This is for the number of buildings built over time. Time span is 10 years.

Say I have 26 buildings planned and want them built over a 10 year period following a normal distribution (few built year one, most built year 5, few built final year). Currently it seems I am only making a bell curve for a dataset of 1-26. How can I create a curve telling me how many should be built year to year following a normal distribution?

Also, an explanation of "cumulative" variable in the NORMDIST formula may help.

Thanks!
