QUESTION 8

1. As Bayes' Theorem illustrates, when you're testing for a rare event (e.g. a rare disease), it's unlikely that a positive result will translate into a high likelihood that the event happened. This is true even for tests which seem very accurate. This counter-intuitive result only works for rare events; why?

a) Because it results in a lot of false positives.

b)Because it causes specificity to fall.

c)Because it causes sensitivity to fall.

d)Because itresults ina lot of false negatives.
