Consider the hypothesis test H 0 : 2 1 = 2 2 against H 1
Question:
Consider the hypothesis test H0: σ21 = σ22 against H1: σ21 > σ22. Suppose that the sample sizes are n1 = 20 and n2 = 8, and that s21 = 4.5 and s22 = 2.3. Use α = 0.01. Test the hypothesis and explain how the test could be conducted with a confidence interval on σ1 / σ2.
