Your answer should be accurate to at least two decimal places. Answer: 0 b) Given the regression line y=6.7+1.2x, and a coefficient of determination of 0.26, what is the coefficient of correlation? Your answer should be accurate to at least two decimal places. Answer: 0 c) Given the regression line y=3.8-5.6x, and a coefficient of determination of 0.68, what is the coefficient of correlation? Your answer should be accurate to at least two decimal places. Answer: 0 Marking: ) Your answer was: 0 The correct answer was: 0.728 The coefficient of correlation R is the either the positive or negative square root of the coefficient of determination R2. It is positive if the dependent positively correlated (indicated by a positive slope of the regression line), and negative if the dependent and independent variables are negatively co slope of the regression line) You will receive no marks for this part. ) Your answer was: 0 The correct answer was: 0.5099 You will receive no marks for this part. c) Your answer was: 0 3 2'C Cloudy ~ 40 144 esc ? # 5 E R lab W LP
