The statement that is a correct interpretation of the word strong in the association is B. the actual time required to deliver all the items to the baggage claim area based on the number of models that are unloaded will be very close to the time predicted by a least square model.
- A linear relationship helps in showing the relationship that exists between two variables.
- A scatter plot is vital as it is a graph that helps in showing the relationship for two numerical values. Apart from the relationship between the variables, it also helps in plotting the data points.
- Since the scatterplot of the two variables indicated a strong, positive linear association, it means the changes that occur to the variables are almost the same. For example, if one of the variables increases by two, then the other variable increases by two also.
In conclusion, the actual time required to deliver all the items to the baggage claim area will be identical to the time predicted by a least square model.
