Inference about slope
We'll make confidence intervals to estimate slope based on sample data. We'll also do significance tests about slope to see if a sample slope is significantly different than 0.
Transformations to achieve linearity
When we have a nonlinear relationship, we can often use logarithms, powers, and roots to transform the data so the relationship becomes linear. This allows us to use least-squares regression and do other inference procedures that we're already familiar with.
