Hypotheses for 1 Variance

For the 1 variance test, the hypotheses are as follows.

Null hypothesis

H₀: σ = σ₀	The population variance (σ) equals the hypothesized variance (σ₀).

Alternative hypothesis

Select one of the following alternative hypotheses.

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).
