WebbFirst, we need the equation for N ( 0, 25), which, by definition, is: f ( x) = N ( μ, σ 2) = N ( 0, 25) = 1 σ 2 π e − ( x − μ) 2 2 σ 2 = 1 5 2 π e − x 2 50. Now, we simply need to integrate this from − x to x, set it equal to .90, and solve for x (our answer): F ( x) = 1 5 2 π ∫ − x x e − x 2 50 d x = 0.9. However, we run ...
