Distribution generation

[imtiyaz]

Hi,
I have a table which has following inputs;
1) Project Name
2) Manhours
3) Start Date
4) Finish Date = Start Date + X month

I require to plot manhours in per month basis on bell curve (0%, 1%, 3%, 8%, 15%, 23%, 23%, 15%, 8%, 3%, 1%) distribution, how do I do it?

Further Explanation as Example;
1) Project Name = Project1
2) Manhours = 10000 mhrs
3) Start Date = 1/1/2006
4) Finish date = Start Date + 10 months (1/10/2006)

How do I plot the Manhours between the ten months based on bell curve.
Also Suppose I want to do it on straightline how do I do it?
Thanks,
Imtiyaz
