Find the equation of the line of best fit and the correlation coefficient for the data shown. (1, 88), (2, 75), (3, 71), (4, 69), (5,66), (6, 68), (7, 50) Regression equation:
Explain your reasoning.
No, it is not reasonable to use the line of best fit to make predictions. The correlation coefficient r = 0.15 is close to 0, which indicates a very weak linear relationship between the variables. Therefore, the line does not fit the data well enough to provide reliable predictions.
