Question 14.35

14.35 Why so small? Make a scatterplot of the following data:

x 1 2 3 4 9 10
y 12 2 3 5 9 11

Use your calculator to show that the correlation is about 0.4. What feature of the data is responsible for reducing the correlation to this value despite a strong straight-line association between x and y in most of the observations?
