5. An Archaeopteryx is an extinct animal having feathers like a bird but also having very prominent teeth. Five fossilized specimen of this creature have been found with the lengths of the femur (a leg bone) plotted against the lengths of the humerus (a bone in the upper arm): Femur Humerus 38 59 64 56 63 70 71 74 76 41 Archeologists have long felt that there should be a positive linear correlation between the lengths of the femur and the lengths of the humerus in these extinct creatures. What do the above data suggest? (A) A positive correlation is likely because lengths of bones in any animal are always positively correlated. (B) A positive correlation is likely at the 5% level of significance. (C) There is no significant positive correlation at the 1% level of significance. (D) There is no significant positive correlation at the 5% level of significance.
