In a regression problem, the following pairs of (x, y) are given: (3, 1), (3, –1), (3, 0), (3, –2), and (3, 2). From this we can determine that: O The correlation between x and y is 1. O The slope of the least-squares regression line is 1. O The correlation between x and y is 0. O The value of is-1
