D.1) The correlation coefficient (r) for the model is

D.2)The coefficient of determination (r^2) for this model

D.3) The percentage of variation in sales that can be explained by TV appearances

demand is 3,6,7,5,10,7 in that order

Mark Garson, owner of musical instrument distributorship, Winks that demand for guitars may be related to the number of television appearances by the popular group Maroon 5 during the previous month.
