10. answer true or false for the following statements. if false, justify what would make the statement true. a. if the least-squares equation relating the independent variable x and the dependent variable y for a given problem is y = 2x + 5, then an increase of 1 unit in x is associated with an increase of 2 units in y. b. if your computed correlation coefficient is r = +1.2, then you have better than a perfect positive correlation. c. a student might expect that there is a positive correlation between the age of his or her laptop and its resale value. d. in simple regression analysis, if the slope of the line is positive, then there is a positive correlation between the dependent variable y and the independent variable x. e. if there is no correlation between the independent and dependent variables, then the value of the correlation coefficient must be –1.
