This example demonstrates how to construct a confidence interval for a normal distribution using GeoGebra. Key math concepts include normal distribution, standard deviation, integral calculation, confidence level, and probability & statistics. GeoGebra commands/objects used are Segment, Normal, Point, Integral, etc. Suitable for high school and above students learning about confidence intervals in probability statistics.

GeoGebra Commands & Parameters

  1. Segment(G, A) → a_1
  2. Normal(μ, σ_1, -0.5) → P1
  3. Point(xAxis) → H
  4. Integral(f, a, b) → Prob
  5. Segment(I, J) → h
  6. Integral(g, 60 - (2 * σ_1), 60 + (2 * σ_1)) → c
