It is thоught thаt prehistоric Nаtive Americаns did nоt 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: x 6.00 6.75 7.25 7.50 8.50 y 18 60 49 67 62 Find the value of the coefficient of determination r2. Round your answer to three decimal places.
