Normal distribution and probability examples
Web1 de jul. de 2024 · The TI probability program calculates a \(z\)-score and then the probability from the \(z\)-score. Before technology, the \(z\)-score was looked up in a standard normal probability table (because the math involved is too cumbersome) to find the probability. In this example, a standard normal table with area to the left of the \(z\) … WebDrawing a normal distribution example The trunk diameter of a certain variety of pine tree is normally distributed with a mean of μ = 150 cm \mu=150\,\text{cm} μ = 1 5 0 cm mu, …
