Final answer:
The New Jersey Plan advocated for equal representation among states, which led to the Connecticut Compromise in which the Senate granted equal representation and the House provided representation based on population.
Step-by-step explanation:
The plan that called for equal representation among the states was the New Jersey Plan. The New Jersey Plan proposed a unicameral (one-house) legislature with equal votes for each state, which contrasted with the Virginia Plan's bicameral (two-house) legislature based on proportional representation. The deadlock between the smaller states' support for the New Jersey Plan and the larger states' preference for the Virginia Plan led to the Connecticut Compromise, which incorporated elements of both plans. This created a bicameral Congress with equal representation in the Senate and representation based on population in the House of Representatives, pleasing advocates of both initial proposals.
