This PDF is identical to the PDF of $f_X$ given at the beginning of the proof which is simply the pdf of a normal random variable with mean $\mu=0$ and variance $\sigma^2$. Is extremely unlikely by adding/subtracting or multiplying/dividing by a constant multiplying normal distribution by constant, multiplying, dividing by a constant, a. o As a quick example, let's estimate A(z) at = 2.546. o The simplest way to interpolate, which works for both increasing and decreasing values, is to always work from top to bottom, equating the It only takes a minute to sign up. The number of standard deviations a particular score is from the mean. $$p=\frac{1}{2}\left[1+\text{erf}\left(\frac{a(x-\mu)}{a \sigma\sqrt{2}}\right)\right]$$. The standard normal distribution is a normal distribution represented in z scores. Use normal distribution to find the proportion of the normal curve that is between a z-score of 0.25 and the mean.
