For the 75 cars on the lot of a used-car dealership, explain why you would expect a positive association, negative association, or no association between the pairs of variables parts a through d.. a. Consider the age of the car and the number of miles on the odometer. What would one expect to be the association between the variables? O A. Positive association because the number of miles on the odometer decreases as the age of the car increases. O B. Positive association because the number of miles on the odometer increases as the age of the car increases. OC. No association because the number f miles on the odometer is not correlated with the age of the car. OD. Negative association because the number of miles on the odometer increases as the age of the car increases. b. Consider the age of the car and the years of life remaining. What would one expect to be the association between the variables? OA. No association because the years of life remaining is not correlated with the age of the car. O B. Positive association because the years of life remaining decreases as the age of the car increases. O C. Positive association because the years of life remaining increases as the age of the car increases. OD. Negative association because the years of life remaining decreases as the age of the car increases. c. Consider the age of the car and the total amount that has been spent on maintenance since the car was purchased. What would one expect to be the association between the variables? O A. No association because the total amount that has been spent on maintenance is not correlated with the age of the car. O B. Positive association because the total amount that has been spent on maintenance increases as the age of the car increases. O C. Positive association because the total amount that has been spent on maintenance decreases as the age of the car increases. OD. Negative association because the total amount that has been spent on maintenance increases as the age of the car increases. d. Consider the weight of the car and the number of miles it travels on a gallon of gas. What would one expect to be the association between the variables? OA. No association because the number of miles it travels on a gallon of gas is not correlated the weight of the car. OB. Negative association because the number of miles it travels on a gallon of gas decreases as the weight of the car increases. O C. Positive association because the number of miles it travels on a gallon of gas decreases as the weight of the car increases. OD. Negative association because the number of miles it travels on a gallon of gas increases as the weight of the car increases.

The mean is less than the median because the dot plot is skewed left. Previous question OB. The mean is less than the median because the dot plot is symmetrical. O D. The mean is equal to the median because the dot plot is symmetrical. O F. The mean is greater than the median because the dot plot is skewed right. ......... N 4 ...
