prediction of gas used from degree-days will be quite accurate.
1. (5.26) The software used to compute the least-squares regression line in Exercise 5.23 says that . This suggests that A. although degree-days and gas used are correlated, degree-days does not predict gas used very accurately. B. gas used increases by cubic feet for each additional degree-day. C.prediction of gas used from degree-days will be quite accurate.
(5.26) The software used to compute the least-squares regression line in Exercise 5.23 says that r^2 = 0.98. This suggests that 2. There is a high correlation between the sex of American workers and their income. (4.22) For a biology project, you measure the weight in grams and the tail length in millimeters of a group of mice. The correlation is r = 0.7. If you had measured tail length in centimeters instead of millimeters, what would be the correlation?Explanation / Answer
(1) C. prediction of gas used from degree-days will be quite accurate.
(2)A .The statement must include whether high income tracks with men or with women.
