WebbThis can be used to compute the cumulative distribution function values for the standard normal distribution . The table utilizes the symmetry of the normal distribution, so what in fact is given is. where a is the value … 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.
WebbFirst, I convert P ( X < b) to be using the standard normal distribution. This gives P ( Z < b − μ σ) = 0.05 or P ( Z < b + 1 2) = 0.05. By looking into a table with all values for ϕ ( z), I found out that b + 1 2 = − 3.29 or b = − 7.58. The solution that was given by the teacher is − 4.29. I don't know what I did wrong? statistics
