The following is part of the computer output from a regression
of monthly returns on Waterworks stock against the S&P 500
Index. A hedge fund manager believes that Waterworks is
underpriced, with an alpha of 2% over the coming month.

1. Predict the value of y if X = 4 . (2
decimal places)
2. Calculate the coefficient of determination . (2
decimal places)
3. Is the following statement true or false?
The coefficient of determination is the proportion of the
variation in y that is not explained by the variation in x.
4. Based upon the Coefficient of Determination,...
