I have a fst project and I don't really know what to put for one of the questions. I have tables for "% of adults who were current smokers, % of teenagers who were current smokers, and a table for each age group that smokes in percent. The question I need to answer is "fit at least 2 mathematical models to your data and use them to make some predictions". I don't know what mathematical models to use, if anyone could help me it would be greatly appreciated.
