Answer 1

[AI-generated answer — Bot GPT 3.5]

Yes, I can be confident that my predicted value will be reasonably close to the actual value. A correlation coefficient of -0.833 indicates a strong negative correlation between the variables, meaning that there is a clear relationship between the data points. This suggests that the line of best fit is a good representation of the data set, so a predicted value based on the line of best fit should be reasonably accurate.
