Question: Let Î±1 > 0, Î±2 > 0, with Î±1 + Î±2 = Î±. Then a. Use this equation to derive a more general expression for

Let Î±1 > 0, Î±2 > 0, with Î±1 + Î±2 = Î±. Then

a. Use this equation to derive a more general expression for a 100(1 - Î±)% CI for m of which the interval (7.5) is a special case.
b. Let Î± = .05 and Î±1 = Î±/4, Î±2 = 3Î±/4. Does this result in a narrower or wider interval than the interval (7.5)?
