This example demonstrates how to construct and analyze confidence intervals for proportions using GeoGebra. It involves core mathematical concepts such as confidence intervals, linear functions, power functions, natural numbers, integers, and hyperbolas. Key GeoGebra commands and objects used in the construction include OrthogonalLine, Point, Line, Intersect, Segment, and Integral. Suitable for high school and above students learning statistical inference and visualization of confidence intervals.

GeoGebra Commands & Parameters

  1. OrthogonalLine(C, xAxis) → b
  2. Point(yAxis) → A
  3. Line(A, xAxis) → a
  4. Intersect(a, b) → E
  5. Segment(A, E) → c
  6. Point(c) → F
  7. Segment(D, C) → d
  8. Point(d) → B
  9. Integral(h, m - (2 * s), m + (2 * s)) → i
  10. Segment(I, J) → j
  11. Point(d, m - (2 * s)) → K
  12. Point(d, m + (2 * s)) → L
  13. OrthogonalLine(K, d) → l
  14. OrthogonalLine(L, d) → p
