the linear relation ship between height of female and shoe size is 0.412
comaritive linear relation ship between the male to female
mlle relationship is just higher than femala, because of the height of the males and shoe size is always greater than female height and shoesoze, this is true.
2) the strength of the linear relation ship between them is male relation > female relation
3) the estimated shoe size based on the height is Y = -9.427+0.111X
