Researchers monitoring the number of wolves and rabbits in a wildlife reserve think that the size of the wolf population depends on the rabbit population, since wolves eat rabbits. Over the years, researchers have collected the following data.

Rabbit population - 61   72     78      76    65     54     39     43 

Wolf population -    26    33     42     49     37     30     24     19

a) Generate a scatter plot for the data with the independent variable on the x- axis
b) Given that the equation of the regression line is y= 0.58x-3.10, how many wolves would the regression equation predict when the number of rabbits is zero?
c) Given that R2= 0.7486, calculate the correlation coefficient. Does it indicate a weak or strong relationship?
d) calculate the residual values of all data points?

When you like a flower, you just pluck it out.
But when you love a flower, you water it daily.
The one who understands this, understands life.

- That's the difference between I like you and I love you.
