No, we cannot be confident that the predicted value will be reasonably close to the actual value. A correlation coefficient of -0.833 indicates a moderate negative correlation between the variables. This means that as one variable increases, the other decreases. However, the strength of this correlation is relatively weak. Thus, the line of best fit may not accurately represent the relationship between the variables and may not accurately predict the unknown value.
