Consider the following competing hypotheses and relevant summary statistics:

H₀: ????²₁ ∕ ????²₂  ≥ 1

H_A: ????¹₂ ∕ ????²₂ < 1

Sample 1: s²₁= 1,315 and n₁ = 17

Sample 2: s²₂ = 1,523 and n₂ = 19

Conduct this hypothesis test at the 5% significance level. State your assumptions. (Hint: You may want to first convert the above left-tailed test into a right-tailed test by switching the two variances.)
