In a survey of 1,000 television viewers, 40% said they watch network news programs. For a 90% confidence level, the margin of error for this estimate is 2.5%. If we want to be 95% confident, how will the margin of error change?

  • The margin of error will remain the same.
  • Since more confidence requires a more narrow interval, the margin of error will be larger.     
  • Since more confidence requires a wider interval, the margin of error will be smaller.
  • Since more confidence requires a more narrow interval, the margin of error will be smaller.
  • Since more confidence requires a wider interval, the margin of error will be larger.
