For every unit increase in height, there is an expected increase of 0.67 units in weight. For every unit increase in height, there is an expected increase of 1.5 units in weight. O For every unit increase in weight, there is an expected increase of 1.5 units in height.Question 23 2 pts Given the estimated simple linear regression of yhat = 5x - 1.
