The given information does not provide the correlation coefficient value. However, in general, the closer the correlation coefficient is to 1 or -1, the more confident we can be in the accuracy of the predicted value using the line of best fit.
A correlation coefficient can range from -1 to 1, with values close to 1 indicating a strong positive correlation and values close to -1 indicating a strong negative correlation. When the correlation coefficient is close to 0, it suggests a weak or no linear relationship between the variables.
If the correlation coefficient is close to 1 or -1, it implies that the data points are tightly clustered around the line of best fit, making the predicted value reasonably close to the actual value. However, if the correlation coefficient is close to 0, the data points are widely scattered, and the line of best fit may not accurately represent the relationship between the variables. In such cases, the predicted value may not be close to the actual value.
Without the specific value of the correlation coefficient provided in the prompt, it is not possible to determine the extent of confidence in the predicted value.
