This example demonstrates how to calculate the confidence interval for a single proportion. Key mathematical concepts include the calculation of confidence intervals in probability and statistics. Using GeoGebra commands such as IndexOf, Segment, and Textfield, users can dynamically adjust the sample proportion and confidence level to observe changes in the confidence interval. Suitable for high school and above students or teachers.

GeoGebra Commands & Parameters

  1. IndexOf(SelectedElement[conf], conf) → ind
  2. Segment((left, 0), (right, 0)) → f
  3. Segment((0, 0), (1, 0)) → g
  4. Textfield(phat) → InputBox1
  5. Textfield(n) → InputBox2
  6. Segment((0, -0.01), (0, 0.01)) → h
  7. Segment((1, -0.01), (1, 0.01)) → i
