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=5.00 5.75 6.25 7.25 8.25 y= 6 16 22 68 82 Find the value of the coefficient of determination
i have an answer of 0.55 is this correct, but a possible answr of 0.945

Using a statistics calculator, I found correlation coefficient r = 0.972; therefore, the coefficient of determination would be r^2 (note: ^2 means squared). Your rounded answer of 0.945 would then be correct.
