WebbInstructions: Compute the inverse cumulative normal probability score for a given cumulative probability. Give a cumulative probability p p (a value on the interval [0, 1]), specify the mean ( \mu μ) and standard deviation ( \sigma σ) for the variable X X, and the solver will find the value x x so that \Pr (X \le x) = p Pr(X ≤ x) = p . Pop. WebbSo it must be normalized (integral of negative to positive infinity must be equal to 1 in order to define a probability density distribution). Actually, the normal distribution is based on the function exp (-x²/2). If you try to graph that, you'll see it looks already like the bell shape of the normal function.
