zes/7987/take/questions/207416 Mar 11 at 8:08pm Instructions Question 6 2 pts 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: x 6.00 6.50 6.75 7.50 8.00 y 9 26 55 62 77 given that r-0.946, -6.95, y-45.8, and Find the value of the coefficient of determination y-182.324+32.824x. O-0.896 O 0.896 -0.054 O 0.054 O 0.946 Previous Next

Explanation / Answer

Given :-  

r=0.946 , Xbar=6.965 , Ybar= 45.8 and

Y^ = -182.324+32.824x

We have to find coefficient of determination.

Therefore,

r2 = (0.946)2 = 0.896

Answer :- 2nd option is correct.
