Question

Using the data in the worksheet Consumer Transportation Survey, develop a contingency table for Gender and Vehicle Driven; then answer the following questions. You must have three pivottables: the contingency table, the joint probability table, and the conditional probability table. What is the probability that respondent is female? 29/50 What is the probability that a respondent drives an SUV? 15/50 What is the probability that a respondent is male and drives a minivan? 1/50 What is the probability that a female respondent drives either a truck or an SUV? 5/29 If it is known that an individual drives a car, what is the probability that the individual is female? 16/22 If it is known that an individual is male, what is the probability that he drives an SUV? 10/21 Determine whether the random variables "gender" and the event "vehicle driven" are statistically independent. The reason that "female" and "driving car" are not independent is because [ Choose ] 5/29 Prob (car | female) is not equal to Prob (female) 10/21 Prob(car | female) is not equal to Prob(car) 29/50 Prob (car | female) is equal to Prob (car) 16/22 Prob (female | car) is not equal to Prob (car) Yes, gender and vehicle driven are independent 15/50 1/50 No, gender and vehicle driven are not independent.

What is the probability that respondent is female?
29/50

What is the probability that a respondent drives an SUV?
15/50

What is the probability that a respondent is male and drives a minivan?
1/50

What is the probability that a female respondent drives either a truck or an SUV?
5/29

If it is known that an individual drives a car, what is the probability that the individual is female?
16/22

If it is known that an individual is male, what is the probability that he drives an SUV?
10/21

Determine whether the random variables "gender" and the event "vehicle driven" are statistically independent.

The reason that "female" and "driving car" are not independent is because
[ Choose ]
5/29
Prob (car | female) is not equal to Prob (female)
10/21
Prob(car | female) is not equal to Prob(car)
29/50
Prob (car | female) is equal to Prob (car)
16/22
Prob (female | car) is not equal to Prob (car)
Yes, gender and vehicle driven are independent
15/50
1/50
No, gender and vehicle driven are not independent.
