Answer to Question 1

Instead of conducting one simple observational study, conduct many observational studies, each looking at smoking and heart attacks from a different angle, for all different populations. Once the entire body of evidence from all these studies is examined, the connection can be seen between smoking and heart attacks.

Answer to Question 2

Observational studies are the only choice here. Experimental data would require the medical researcher to randomly assign some people to smoke and others not to smoke. This of course is not ethical.
