Question
Make a scatterplot and find the correlation coefficient. Do you think all five specimens come from the same species?
Archaeopteryx is an extinct beast having feathers like a bird but teeth and a long bony tail like a reptile. Only six fossil specimens are known. Because these specimens differ greatly in size, some scientists think they are different species rather than individuals from the same species. If the specimens belong to the same species and differ in size because some are younger than others, there should be a positive linear relationship between the lengths of a pair of bones from all individuals. An outlier would suggest different species. Here are data on the lengths in centimeters of the femur and the humorous for the specimens that preserve both bones: Femur 38 Humorous 41 63 56 59 64 70 74 72 84 Make a scatterplot and find the correlation coefficient.
