Calculating Confidence Interval with Python

**Which values can we estimate using a confidence interval?**

Within this course, we will estimate mean values, but you can estimate whatever you want: variances, math expectations, etc.

Let's discuss the function for finding confidence intervals.

`st.norm.interval()`

- function that calculates confidence interval with the parameters:

`alpha`

parameter is the**level of confidence**,`loc`

parameter is the**mean value of the distribution**.`scale`

is the**value of standard error of the mean**.

**What does standard error of the mean means?**

The standard error of the mean, or standard error, demonstrates how the population mean is likely to vary from a sample mean.

Try to change the `alpha`

parameter and observe the changes.
