A set of data has a correlation coefficientr = 0.15. Is it reasonable to use the line of best fit to make predictions from the data?yesno Explain your reasoning.

Answer:

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.
