Given the y = 94.38x + 38.17 with an r-value of 0.9948, it can predict the value of stock ABC in any x days. First, evaluate r^2. R^2 = (0.9948)(0.9948) =
0.98962704. R^2 is a statistical measure of the fitness of the data in a regression line. A value of almost 1 means, the scatter plot is almost liner. Fot this problem, by substitution the answer is B, $4474.03.
