approximately normal with mean given by µ 0 (assume that µ 0 is 50 for the next examples) from the null hypothesis, and standard deviation sigma/Sqrt[n] (which equals 5/Sqrt[36]=5/6). Step 1: Based on ...

We can see a bigger difference between the means. If MASH workshops don’t make a difference, this result is more unlikely than either of the two above examples. Therefore, the p-value would now be ...

In the decades since its introduction, the neutral theory of evolution has become central to the study of evolution at the molecular level, in part because it provides a way to make strong ...

Confidence intervals and hypothesis tests are directly linked. Confidence intervals can be used to check the reasonableness of claims about the parameter. If someone claims the parameter is equal to ...

The first thing any scientist does before performing an experiment is to form a hypothesis about the experiment's outcome. This often takes the form of a null hypothesis, which is a statistical ...

Students will analyze information from a variety of sources in order to create a hypothesis about the origin of an interesting family artifact. Students will create alternative hypotheses based ...
