WebbAn normal distribution has mean μ and variance σ 2. A normal distribution with μ=0 and σ=1 is called standard normal distribution. The cumulative distribution function (cdf) evaluated at x, is the probability that the random variable (X) will take a value less than or equal to x. The cdf of normal distribution is defined as: Webb21 jan. 2024 · Find each of the probabilities, where z is a z-score from the standard normal distribution with mean of μ = 0 and standard deviation σ = 1.
