#### How do you find the normal distribution of a function?

The following is the plot of the standard normal probability density function. Note that this integral does not exist in a simple closed formula….Normal Distribution.

Mean | The location parameter μ. |
---|---|

Median | The location parameter μ. |

Mode | The location parameter μ. |

Range | -\infty to \infty. |

Standard Deviation | The scale parameter σ. |

**How do you find the normal distribution of a CDF?**

The CDF function of a Normal is calculated by translating the random variable to the Standard Normal, and then looking up a value from the precalculated “Phi” function (Φ), which is the cumulative density function of the standard normal. The Standard Normal, often written Z, is a Normal with mean 0 and variance 1.

## What is the CDF of normal distribution?

**How do you graph in terms of Y on a TI-84 Plus?**

Press the PRGM button on your TI-84 calculator and locate the “XGRAPH” entry in your program list. Press the ENTER key, causing “prgmXGRAPH” to appear on your screen; press ENTER again to launch the app. When prompted, enter your equation but use the letter X instead of Y.

### How do you create a normality plot?

How to Draw a Normal Probability Plot

- Arrange your x-values in ascending order.
- Calculate fi = (i-0.375)/(n+0.25), where i is the position of the data value in the. ordered list and n is the number of observations.
- Find the z-score for each fi
- Plot your x-values on the horizontal axis and the corresponding z-score.

**What is the z-score for 95 confidence interval?**

-1.96

The critical z-score values when using a 95 percent confidence level are -1.96 and +1.96 standard deviations.
