Question
It is thought that prehistoric Indians did not take their best tools, pottery, and
household items when they visited higher elevations for their summer camps. It is
hypothesized that archaeological sites tend to lose their cultural identity and
specific cultural affiliation as the elevation of the site increases. Let x be the
elevation (in thousands of feet) for an archaeological site in the southwestern
United States. Let y be the percentage of unidentified artifacts (no specific cultural
affiliation) at a given elevation. Suppose that the following data were obtained for
a collection of archaeological sites in New Mexico:
5.75
6.25
6.75
7.75 8.25
