The mean and standard deviation for male human births in the U.S. from 1995 to 2012 are x = 245,673 and sx = 28,357. The mean and standard deviation for female human births in the U.S. for the same time period are = 251,785 and sy = 25,437. The correlation coefficient is r = 0.91. Find the equation for the least-squares regression line for male to female human births.
