A company is doing a hypothesis test on the variation of quality from two suppliers. Both distributions are normal, and the populations are independent. use $\displaystyle \alpha$ = 0.01

H₀ : $\displaystyle \sigma$ ₁ ² = $\displaystyle \sigma$ ₂ ²
H_A : $\displaystyle \sigma$ ₁ ² > $\displaystyle \sigma$ ₂ ²

The standard deviation of the first sample is 5.514
6.7899 is the standard deviation of the second sample.

The test statistic is =
