Suppose you compute the correlation coefficient between two variables, X and Y, and obtain a value of 0.55. Then you realize that all the values for both variables have been corrupted in a way that their actual sign has been changed (positive values were turned into negative values and vice versa; only the signs have been changed). Then the actual, corrected value of the correlation coefficient .

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36
