Why do some states have more representatives than other states?

This is because of proportional representation.

The legislature is composed of the Senate and the House of Representatives. The Senate is considered the state's house, and elects the same number of representatives for each state, so as to maintain the equality of states in their demands.

However, the house of representatives elects deputies in a proportional way, that is, the states with the highest population density elect more representatives than the less populous states. It is a reasonable measure that maintains the proportionality of representation.

answer; by working independently, the states have a high likelihood of developing innovative solutions that can be employed in other states;

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
