A research group examined the potential survival effect of an anti-viral drug, Ribavirin, against rabies infection in an animal model, using randomised control and Ribavirin-treated groups. Their data are provided in "trials_data.txt".

1. Using a software program of your choice, construct a contingency table of their results,
2. Then use an appropriate statistical test to determine whether treatment with Ribavirin can protect individuals infected with rabies.
3. Report your contingency table, the reasoning behind the choice of statistical test, and your conclusion
