Statistics math problem example.

"The average lifespan of a fruit fly is between 1 day and 10 years" is an example of a confidence interval, but it's not a very useful one. From scientific measures to election predictions, confidence intervals give us a range of plausible values for some unknown value based on results from a sample. Let's learn to make useful and reliable …

Definition: Simple Sample Spaces. A simple sample space refers to a finite sample space where all of the outcomes are equally likely. Example 2 4.1.1. Suppose an experiment consists of flipping a fair coin. Then S = {H, T}. This sample space is finite and since the coin is fair, both outcomes are equally likely.The Range (Statistics) The Range is the difference between the lowest and highest values.
