That is, a sample size of 100 in a population of 10,000 will have almost the same margin of error as a sample size of 100 in a population of 10 million.
There are many ways Congress sought to limit the power of the executive branch. These are as follows: 1) Congress can override the veto of the president; 2) Congress can refusâ¦e to confirm presidential appointments; 3) Congress can impeach the president; 4) Congress can refuse to ratify presidential treaties.
This is one example of how the executive branch can 'check' congressional powers. But Congress can check the president, too. For example, the Senate must approve presidential nominations to federal posts and must ratify all treaties by a two-thirds vote.
