Question: The following scatter plot was created for two characteristics of a sample of automobiles, weight and miles per gallon.  After looking at the graph, what can you conclude about the relationship between the two characteristics?

  1. The correlation coefficient is approximately +1.
  2. The correlation coefficient is approximately  -1.
  3. The correlation coefficient is approximately 0.
  4. One can’t estimate the correlation coefficient from the graph.

If there is no correlation between a dependent variable (Y) and an independent variable (X), can one predict Y knowing X?  What is the best guess for Y?
