I want to have a bell curve showing 1000 people distributed over a time duration. How is it possible in excel?

Specifically, I want to have my x-axis to be a time duration for example running between 4pm - 6pm with an increment of 1 minute
On the Y axis I want to show the number of people. So if there are 1000 people in total then according to normal distribution there will be a bell curve showing number of people at any minute in the above mentioned time duration.

How do I achieve it in Excel.
