In the video below, we’ll go over the standard normal distribution as well as some equations you should be familiar with. After that, we will work on some problems so you can see how you can use these formulas well. That is, the normal distribution is in the form of a bell curve. It looks something like this.

Now the notation for that. Maybe you’ve seen this in your book. Here is the random variable X. So for a normal distribution you have two important parameters you need to know. This is the mean and standard deviation represented by the symbol Sigma. It’s a bit like Theta, but there it is. Now the mean is right in the middle of the bell curve.

And here that’s going to be 1 standard deviation from the mean, and here it’s going to be about 1 standard deviation from the mean. On the left, the Z score corresponding to 1 standard deviation is just one. When X is less than the mean, Z scores are negative, so 2 standard deviations from the mean Z equals 2.

Let’s say this is 3 standard deviations from the mean, so Z will be 3, and the same goes for the other side. Now the formula you need to calculate the Z score is this Z. This is a horrible looking Z. Let’s do that again, Z equals X.

Minus the mean divided by the standard deviation. Sometimes you need to calculate that XX equals the mean plus Z times the standard deviation. These are some formulas you’ll want to make sure you write down for the problems I’ll give you later, the probability density function for the normal distribution.

Is this function? Here, F(X) equals 1 over standard deviation times sqrt, 2π times E to minus 1/2 * X minus the mean divided by standard deviation squared. And remember that E is a number, approximately 2.718. This continues now.

**What Percent Of A Standard Normal Model İs Found İn Each Region? Draw A Picture First.** – You won’t need this formula in a normal statistics course, you just need to know that it’s a PDF or probability density function for a normal distribution. However, unless you’re using it with math or something, you don’t really need to use it to calculate the answer. It includes integral calculus to calculate probabilities with this formula. I actually did this in another video on YouTube, you can find it. It was probably posted about a year ago or so.

If you want to learn how to use the account to get the answer. But for this particular video, we won’t go into that much detail. But just in case, if you see a question in a test, at least you know that this formula corresponds to a normal distribution. There is such a thing as the empirical rule, you need to be familiar with it. So the empirical rule tells us that we have 68% of the X values.

Lie within one standard deviation of the mean. 95% of the X values are within two standard deviations of the mean and 99.7% of the X values are within 3 standard deviations of the mean. So knowing this, how do you calculate it?

**What Percent Of A Standard Normal Model İs Found İn Each Region? Draw A Picture First.** / The area under the curve expressed as a percentage in each of these segments. Well, if the area here is 68%, if we divide it into two, this area should be 34% together with the left side. Now, excuse me, what is the percent area for these two regions?

To find this answer, you need to subtract these two numbers, 95 – 68. Now it is important to understand that the area of a continuous probability distribution function is 1, that is, the area of this region.

It will be a decimal value. 0.135. The same goes for this region here, so keep that in mind. The total area under the curve is equal to 1. Now what is the probability of finding an X value in these two regions? What we have to do is subtract these two numbers by 99.7 – 95, which will give us 4.7, and then we’ll divide that by two.

**What Percent Of A Standard Normal Model İs Found İn Each Region? Draw A Picture First.** – So you should get 2.35%. This is the probability of finding or getting an X value in that region. Now the remaining parts. By the way, this must be like very close to the X-axis. My drawing wasn’t perfect, but to find the remainder, it’s going to be 100 minus 99.7, which is .3. Divide this in half and.

And so there is a 15% chance of finding an OR to get an X value beyond three standard deviations. So these are values when using the empirical rule to solve probability questions about the normal distribution. We’ll talk about how to use this chart later in this video. **https://www.chegg.com/homework-help/questions-and-answers/percent-standard-normal-model-found-region-draw-picture-first-z-11-dz-105-c-05-q44361230**
