**Question 1:** 

A new drug is being sold to treat anxiety, with a possible side effect being hypercholesterolemia.

The first time is when treatment begins with a placebo condition (i.e., *before* taking the drug; not to be confused with a placebo pill). The second time is *after* a month of taking the drug on a regular schedule. The results of the cholesterol levels for all 6 patients at both times are listed in the table above.
