Determining the margin of error requires a random sample of a population of n and a desired confidence level.
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
MOE=95%2Fsqrt%281000%29
MOE= ±3.004163% ...round it
MOE=±3%



so, your answer is:
a. ±3%
