Question 3. A city is studying the role of drug use on vehicle accidents. The officials obtain experimental research results that suggests that driving under the influence (DUI) culminates in accidents more frequently than driving sober (~DUI) P(Accident DUI) : = 0.4 whereas P(Accident |~DUI) = 0.1 Suppose that anonymous survey research suggests how prevalent driving under the influence is in the city, P (DUI) = 0.25. i) ii) iii) Show that Accident and DUI are not statistically independent variables. Find how likely it is that an accident in this city involved a driver who was under the influence, P (DUI Accident). For the two conditional probabilities, P (Accident|DUI) and P(DUI|Accident), explain which relationship between the events is a causal one, and which is an inferential one.
