Beer Report Part 2

In my original scatterplot I had the outlier at 0,0 removed. A 0.1 significance level is appropriate level because it is precise.

Line of Best fit y = mx + 100.

Scatter Plot 1 has the outlier removed.

Scatter Plot doesn't.

It is a good fit for the data. The data is correlated. The correlation does cause causation.

need to draw the fitted model on the scatterplot to show the fit of the regression.
