This example demonstrates how to calculate the inverse normal probability using GeoGebra, visually showing the critical value for a given probability in a normal distribution. Core math concepts include normal distribution, probability density function, integral, and expected value. It utilizes commands like Normal, InverseNormal, Integral, and LaTeX, along with objects such as μ (mean), σ (standard deviation), f (density), p (probability), a, b (integral bounds), P (probability value), and various text/graph objects. Suitable for high school and above students learning probability & statistics, focusing on normal distribution inversion and applications.

GeoGebra Commands & Parameters

  1. Normal(μ, σ, x, false) → f
  2. InverseNormal(μ, σ, p) → a
  3. Integral(f, -100, a) → b
  4. InverseNormal(μ, σ, 1 - p) → d
  5. Integral(f, d, 100) → e
  6. InverseNormal(μ, σ, 0.5 + q_1) → h
  7. LaTeX(p_1, true, true) → text3
  8. Integral(f, (-h), h) → i
