Instead of the age of a vineyard, considered in Exercise 27, perhaps the Size of the vineyard

Question:

Instead of the age of a vineyard, considered in Exercise 27, perhaps the Size of the vineyard (in hectares) is associated with the price of the wines. Look at the scatterplot:

150 125 100 75 50 25 + 100 25 50 75 125 Size (hectares) Case Price


a) The correlation is -0.022. Does price get lower with increasing vineyard size? Explain.

b) If the point corresponding to the largest vineyard were removed, what effect would that have on the correlation?
