Consider the hypothesis test Ho: o = 2 against H₁:0² < 62. Suppose that the sample sizes are n₁ = 5 and n₂ = 10 and that s² = 23.7 and s = 29.6. Use α = 0.05. (a) Test the hypothesis. Ho rejected. (b) Find a 95% confidence interval on o2/o2. Round your answer to two decimal places (e.g. 98.76). 676 i
