Final answer:
In a scatterplot that shows no association, predictions cannot be made because there is no pattern or trend to indicate a relationship between the x and y variables.
Step-by-step explanation:
In a scatterplot that shows no association, predictions cannot be made because there is no pattern or trend to indicate a relationship between the x and y variables. A scatterplot with no association means that the data points are randomly scattered and there is no relationship or correlation between the variables being plotted. Therefore, it would not be appropriate to make predictions based on such a scatterplot.
