Assumes a 95% level of confidence.
so, you can compute the margin of error %28MOE%29 using this formula:
MOE=t%2Fsqrt%28n%29 where t is a desired confidence level and n is a random sample of a population
if n=500 and t=95%
MOE=95%2Fsqrt%28500%29
MOE= ±4.2485291% ...round it
MOE=±4%


so, your answer is:
b. ±4%
