EPIDEMIOLOGY QUESTIONS
1.) Scenario: Substance A has an associated increasedhealth risk of 20% and the increased risk associated with substanceB is 15%. When studied together, the increased risk associated withbeing exposed to both substance A in conjunction with substance Bis 70%.
Question: Â Â Is the health risk associated withthis combination of substances synergistic? (i.e., Does itdemonstrate synergy?)
2.) In at least 10-12 sentences, please explain youranswer to the previous question on synergy. Be sure to support youranswer with relevant information. Be sure to define basic terms andexplain the relevance of your finding. Also, illustrate your answerwith an appropriate mathematical example using substance A and Bbased on the data provided in the previous question!
3.) In at least 12-15 sentences, please explain why itis not always possible for epidemiologists to use an experimentaldesign such as the RCT to test a hypothesis about an exposure onhumans. Also as part of this, please use at least onescholarly(peer reviewed) journal article to substantiate yourviews.
