H0: σ2 = σ20 | The population variance (σ) equals the hypothesized variance (σ0). |
H1: σ2 ≠ σ20 | The population variance (σ) differs from the hypothesized variance (σ0). |
H1: σ2 > σ20 | The population variance (σ) is greater than the hypothesized variance (σ0). |
H1: σ2 < σ20 | The population variance (σ) is less than the hypothesized variance (σ0). |
