You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your data set is Negative 0 point 833. Can you be confident that your predicted value will be reasonably close to the actual value? Why or why not?
No, a correlation coefficient of -0.833 indicates a strong negative linear relationship between the variables. This means that as one variable increases, the other variable decreases. While a line of best fit can still be used to make predictions, the high negative correlation suggests that the predictions may not be as accurate or reliable compared to a data set with a correlation coefficient closer to 1. Therefore, it is unlikely that the predicted value will be reasonably close to the actual value.
