isn't it the area under the curve for these tails?

and, imagine a PDF that isn't so peaked and a "large" p-value. It would be great if you would show the code to calculate the actual p-value (rather than just eye-balling it)

typo

this is a good place to describe the concept of p-value and a null hypothesis

"Based on the assumption of no difference between treatments, it is the probability of seeing the observed difference or a bigger one." https://twitter.com/tomboylesid/status/1510002848003772418

code?

{delete comma}

typo

suggest moving the first equation prior to the "to interpret the intercept" paragraph and add eta sub i for completeness

then delete the strange right pointing arrow in front of the second equation.
