Hypothesis Testing,e relationships between variables (Chapter .), and evaluated confidence intervals?– projecting sample statistics back onto population parameters (Chapter .). You even visually evaluated two samples for whether or not they came from the same population. Admittedly that evaluation was visual; it is time to refine that idea and make it rigorous.
