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 -0.833. Can you be confident that your predicted value will be reasonably close to the actual value? Why or why not?
No, you cannot be confident that your predicted value will be reasonably close to the actual value. A correlation coefficient of -0.833 indicates a strong negative correlation between the variables, but it does not guarantee the accuracy of the prediction. The line of best fit represents the general trend of the data, but it may not accurately capture individual data points. Additionally, other factors, such as outliers or non-linear relationships, can also affect the accuracy of the prediction.
