Suppose that a researcher is interested in the average standardized test score for fifth graders in a local school district. The fifth graders at a specific school would comprise a _Sample _ and their average test score would be a _Statistic_.
Any measurement from a sample is called statistic. hence the blanks are filled accordingly.
In both exterior and interior angles on the same side of the transversal, one of the angles will be acute and the other one will be obtuse making them different. Therefore, there is no relationship between them.
