How does the confidence level of an interval influence the width of that interval?

  • Higher confidence level leads to a narrower interval
  • Higher confidence level leads to a wider interval
  • Higher confidence level makes the interval skewed
  • It does not influence the width
The higher the confidence level, the wider the interval. This is because to be more confident that we've captured the true population parameter, we need to provide a wider range of possible values.
