A February 2009 poll conducted by the Marist College Institute for Public Opinion in Poughkeepsie, New York, asked a random sample of 2071 U.S. adults who or what was responsible for a company's failure or success. Of those surveyed, 70% attributed a company's failure or success to the decisions of its top 1executives. The poll asked the same question of a random sample of 110 business executives. Among executives, 88% said that top executives were responsible for a company's success or failure. Marist reported that the margin of error for one of these results was ±9 percentage points and for the other it was ±2.5 percentage points. Which result had the margin of error of ±9 percentage points? Explain your answer.
