For a certain population, a health and nutrition survey finds that: the average weight is 175 pounds with a standard deviation of 42 pounds, the average height is 67 inches with a standard deviation of 3 inches, and the correlation coefficient is 0.7. Furthermore, the scatterplot of height on weight is an oval-shaped cloud of points. Set up the regression equation that predicts weight based on height, and express it in slope-intercept form.
