(b) Find the correlation coefficient. (Round your answer to 3 decimal places. A negative value should be indicated by a minus sign.) (c-1) To test the correlation coefficient for significance at a = 0.05, fill in the following. (Use the rounded value of the correlation coefficient from part b in all calculations. For final answers, round fecale to 3 decimal places and the p-value to 4 decimal places. Negative values should be indicated by a minus sign.) tcalc p-value 0.0002
