WebNov 5, 2024 · x – M = 1380 − 1150 = 230. Step 2: Divide the difference by the standard deviation. SD = 150. z = 230 ÷ 150 = 1.53. The z score for a value of 1380 is 1.53. That means 1380 is 1.53 standard deviations from the mean of your distribution. Next, we can find the probability of this score using a z table. WebThe pnorm function gives the Cumulative Distribution Function (CDF) of the Normal distribution in R, which is the probability that the variable X X takes a value lower or equal to x x. The syntax of the function is the following: pnorm syntax pnorm(q, mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE)

Normal Distribution Examples, Formulas, & Uses

WebA cumulative distribution function (CDF) describes the probabilities of a random variable having values less than or equal to x. It is a cumulative function because it sums the total likelihood up to that point. Its output always ranges between 0 and 1. CDFs have the following definition: CDF (x) = P (X ≤ x) Webwhere x and μ are 1-by-d vectors and Σ is a d-by-d symmetric, positive definite matrix.
