Answer to Question 1

FALSE

Answer to Question 2

Since the coefficient of determination R2 = 0.325, this means that only 32.5 of the variation in weekly sales is explained by this simple linear model, while 67.5 remains unexplained. We may conclude that the simple linear model does not provide a good fit to this data set.
