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: Given that and what percentage of the variation in y can be explained by the corresponding variation in x and the least-squares line? 1.5% 87.8% 5.2% You Answered You Answered 77.1% Correct Answer Correct Answer 12.2% 1 / 1 pts Question 8 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.

Since about 59.2% of the behavior of the y variable can be explained by the corresponding behavior of the x variable if we use the equation of the least- squares line, the line should be used for predictions. Since about 35.0% of the behavior of the y variable can be explained by the corresponding behavior of the x variable if we use the equation of the least- squares line, the line should not be used for predictions. Correct! Correct! Since about 59.2% of the behavior of the y variable can be explained by the corresponding behavior of the x variable if we use the equation of the least- squares line, the line should not be used for predictions. Since about 40.8% of the behavior of the y variable can be explained by the corresponding behavior of the x variable if we use the equation of the least- squares line, the line should be used for predictions. Since about 40.8% of the behavior of the y variable can be explained by the corresponding behavior of the x variable if we use the equation of the least- squares line, the line should not be used for predictions. 0 / 1 pts Question 9

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
