Confidence Interval and Prediction Interval – Learn It 3

  • Find and interpret the confidence interval for the mean response
  • Find and interpret the prediction interval for an individual response
  • Identify whether a confidence interval or a prediction interval is more appropriate in context of the problem
  Penguin A ([latex]202[/latex] mm) Penguin B ([latex]172[/latex] mm)
[latex]92[/latex]% Confidence Interval [latex](4218, 4293)[/latex] [latex](2679, 2851)[/latex]
[latex]92[/latex]% Prediction Interval [latex](3560, 4950)[/latex] [latex](2070, 3460)[/latex]

Let’s use these intervals to describe the relationship between the confidence interval for the mean response and the prediction interval for an individual observation.
