The robust australopithecines are called _________ by the American Anthropological Association.Group of answer choicesOrrorin.Sahelanthropus.Gigantopithecus.Paranthropus.

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.
