The slope of the least squares regression line is given by 5916\" one answer\" 10 points 3 7._v 3: where r is the correlation coefficient, sI is the standard deviation of the X-values, and 5V is the standard deviation of the Yvalues. If r = 0.75, s = 3, and sy = 2, then how much should we expect Y to increase for every one unit of I increase in X? A. O 0.5 units B. O 1.125 units C. O 0.75 units D. O 0.67 units
