Consider the following hypothesis test. H0: σ12 = σ22 Ha: σ12 ≠ σ22 (a) What is your conclusion if n1 = 21, s12 = 4.2, n2 = 26, and s22 = 2.0? Use α = 0.05 and the p-value approach. b)Repeat the test using the critical value approach.

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown
