H0: σ = σ0 | The population variance (σ) equals the hypothesized variance (σ0). |
H1: σ ≠ σ0 | The population variance (σ) differs from the hypothesized variance (σ0). |
H1: σ > σ0 | The population variance (σ) is greater than the hypothesized variance (σ0). |
H1: σ < σ0 | The population variance (σ) is less than the hypothesized variance (σ0). |
