H_{0}: σ^{2} = σ^{2}_{0} | The population variance (σ) equals the hypothesized variance (σ_{0}). |
H_{1}: σ^{2} ≠ σ^{2}_{0} | The population variance (σ) differs from the hypothesized variance (σ_{0}). |
H_{1}: σ^{2} > σ^{2}_{0} | The population variance (σ) is greater than the hypothesized variance (σ_{0}). |
H_{1}: σ^{2} < σ^{2}_{0} | The population variance (σ) is less than the hypothesized variance (σ_{0}). |
