This worksheet is used to find P-values and critical values for chi-squared distribution hypothesis tests. Users can input degrees of freedom and the test value, and the worksheet will display the results using built-in functions and commands. Suitable for statistics and probability theory education.

GeoGebra Commands & Parameters

If(x < 0, 0, (x^(varDF / 2 - 1) * exp((-x) / 2)) / (2^(varDF / 2) * gamma(varDF / 2))) → f
InverseChiSquared(varDF, 1 - varAlpha) → CV
Integral(f, varTV, 999) → P
Textfield(varDF) → DF
Textfield(varTV) → TV
Textfield(varAlpha) → textfield1
Integral(f, CV, 999) → alpha

AI Drawing Prompt Reference

Draw the chi-squared distribution function, input degrees of freedom and test value, and calculate and display the P-value and critical value. First, plot the chi-squared distribution function f, then calculate the critical value CV based on degrees of freedom and significance level, next calculate the integral from the test value to infinity to get the P-value, and finally display the input fields for degrees of freedom, test value, and significance level, and calculate the integral from the critical value to infinity to get the significance level alpha.

The prompt above was compiled from the original drawing commands and is for reference only.
