The following data was collected by Austrailian researchers and published in the Australian Journal of Zoology. The data shows the nasal width and nasal length of a specific species of male gray kangaroo. Researchers used this data to determine if a particular kangaroo skull belonged to this species of kangaroo. They found that kangaroo skulls from other species did not follow this same data trend.If a kangaroo skull had a nasal length of 630 mm and a nasal width of 235 mm, does it appear that this skull is from this specific species of male gray kangaroo?Group of answer choicesYes. By looking at the graph we can see if a skull has a nasal length of 630 mm the nasal width varies between about 200 and 250. Since 235 mm in within this range, the skull is probably from this species.No. A quadratic trendline would have been better for this data. So the prediction given by the trendline is not accurate.Yes. If you use 630 mm as the input of the trendline, you get a predicted nasal width of 234.8 mm. This shows the skull is probably from this species.No. If you use 235 mm as the input for this trendline, you get a predicted nasal length of 114.0 mm. Since this skull has a nasal length of 630 mm, the skull if very different from the data shown in the graph. The skull is probably from a different species of kangaroo.No. If you use the linear equation to predict the nasal width of a male gray kangaroo with a nasal length of 630 mm you get 227.6 mm. Since this skull is 235 mm it is probably not the same species.

Proof Found in Australia Links Humans to DinosaursThe Australian Society for the Study of Subcutaneous Cultures (ASSSC) today released information about the discovery of a previously unknown species of human that could provide more insight to when humans first walked the earth. A complete skeleton found on the Coast Plains, near Melbourne, has anthropologists excited about the possibility of adding another link to the chain of human history. Scientist Peter L. Reilly describes the find: "This mammal, which we have named Homo jurassicus parkus, appears to share several similarities with both modern humans and Jurassic-era dinosaurs. The skull shape, for instance, measures only 1/15th of a centimeter larger than the common Homo sapiens skull, and the metatarsal bones of the feet share a distinctive pattern with those identified from fossils belonging to Compsognathus, a genus of small, bipedal, carnivorous dinosaurs that are believed to have lived over 150 million years ago." Researchers have been flocking to the Canady site in hopes of finding more proof that dinosaurs and humans share a deeper connection than previously thought.Why might people accept this article as fact?A.It refers to the names of real people and places.B.It quotes a scientist who seems to know a lot about the topic.C.It includes information that people find interesting.D.It uses short sentences that give a lot of information.SUBMITarrow_backPREVIOUS
