Since, in general, the longer a car is owned the more miles it travels one can say there is ______ between age of a car and milege.
a positive association,
no association,
a negative association,
a scattered association
Positive, since both are increasing together.
postive
In order to determine the relationship between the age of a car and its mileage, one can perform a statistical analysis. Specifically, we can use correlation analysis to understand the association between these two variables.
To do this, you need to collect data on the age and mileage of a sample of cars. The age can be measured in years, and the mileage can be measured in miles. Make sure to choose a random and representative sample of cars to ensure accurate results.
Once you have the data, calculate the correlation coefficient (usually denoted by "r"). This value ranges from -1 to 1, where a value close to -1 indicates a strong negative association, a value close to 1 indicates a strong positive association, and a value close to 0 indicates no association.
If the correlation coefficient is close to 1, it suggests a positive association, meaning that as the age of a car increases, its mileage tends to increase as well. This could be because older cars are more likely to have been driven more.
On the other hand, if the correlation coefficient is close to -1, it indicates a negative association, which means that as the age of a car increases, its mileage tends to decrease. This could be due to older cars being driven less frequently.
Lastly, if the correlation coefficient is close to 0, it suggests no association between the age of a car and its mileage. In other words, there is no clear relationship between these two variables.
Therefore, based on the correlation analysis, we can conclude that there is a positive association between the age of a car and its mileage.
