Choose the best answers. a. The slope of the regression line will probably be near 0.5. b. As x increases, y probably increases also. c. The slope of the regression line is probably positive. d. There is probably no correlation between x and y. e. The dots on the scatterplot are randomly placed a" over the page. D t. The slope of the regression line is probably negative. O 9. There is probably a negative correlation between x and y h. The dots on the scatterplot are probably rising. i. The dots on the scatterplot are probably falling. I. As x increases, y probably decreases. -) k. There is probably a positive correlation between x and y. 5

Explanation / Answer

The Pearson correlation coefficient, r, can take a range of values from +1 to -1. A value of 0 indicates that there is no association between the two variables. A value greater than 0 indicates a positive association; that is, as the value of one variable increases, so does the value of the other variable. A value less than 0 indicates a negative association; that is, as the value of one variable increases, the value of the other variable decreases.

b,c,h & k are the correct answers
