Question

A July 2011 Gallup poll based on the responses of 1500 adults indicated that 46% of Americans approve of the job Barack Obama is doing as president. One way to summarize the findings of the poll is by saying, “It is estimated that 46% of Americans approve of the job Barack Obama is doing as president. This estimate has a margin of error of plus or minus 3%.” How could you explain the meaning of this to someone who has not taken a statistics course?
