Were the individuals that attended the Constitutional Convention broadly representative of the entirety of U. S. society at the time?

No

Explanation:

The individuals that attended the Constitutional Convention were not representative of the entirety of U. S. society at the time. These delegates were all male, white, free and wealthy. Therefore, they represented only a small percentage of the society of the time. This also means that their view was a narrow one, and that the interests they pursued did not necessarily respond to the interests of the majority of the population.
