IB Maths AI SL 4.11 Hypothesis testing
Students practise conducting hypothesis tests—including chi-squared, t-, and binomial tests—and writing conclusions in context.
How this is tested
- state H₀ and H₁ correctly—e.g., H₀: φ = 0.45, H₁: φ > 0.45 for a one-tailed binomial proportion test
- use a chi-squared test for independence and interpret the p-value
- choose the correct test by matching the statistical context and data type
