Early humans were similar in shape to most modern large primates. The data beloware average male hind limb and forelimb lengths for different species of earlyhominids (humans and their ancestors.) 
a) What is the value of the correlation coefficient for these data?
b) What is the equation of the least squares line describing the relationship betweenx = hind limb length and y = forelimb length.c) Suppose these species are representative of all species of early human ancestors.If a new homonin species dating from about the same time were to be discoveredwith an average hind limb length of 500 mm, what would you predict to be theaverage forelimb length of this species?
