Which Survey Needs a Larger Sample Size: Manhattan vs. Nome or Manhattan vs. San Francisco?

It is difficult to determine the exact sample size without additional information. However, generally speaking, 'Survey B' would likely require a larger sample size compared to 'Survey A'. This is because San Francisco is a much larger and more populated city compared to Nome, Alaska. Therefore, in order to accurately represent the preferences of CSSW students for living in either Manhattan or San Francisco, a larger sample size would likely be needed.
