Using the data in the Excel file Consumer Transportation Survey, develop a contingency table for Gender and Vehicle Driven; then convert this table into probabilities.
- What is the probability that respondent is female?
- What is the probability that a respondent drives an SUV?
- What is the probability that a respondent is male and drives a minivan?
- What is the probability that a female respondent drives either a truck or an SUV?
- If it is known that an individual drives a car, what is the probability that the individual is female?
- If it is known that an individual is male, what is the probability that he drives an SUV?
- Determine whether the random variables “gender” and the event “vehicle driven” are statistically independent. What would this mean for advertisers?
