your teacher will grade your resposnes to the following questions to ensure you recieve proper credit for your answers, you use a line of best fit for a set of data to make a prediction about an unknown value. the correlation coefficent for your data set is -0.833 can you be confident that your predcited value will be reasonnably close to the actual value why or why not
Based on the given information, the correlation coefficient for the data set is -0.833. This value indicates a moderate negative correlation between the variables.
When using a line of best fit to make a prediction about an unknown value, the closer the correlation coefficient is to -1 or 1, the more confident we can be in the predicted value. A correlation coefficient of -0.833 suggests a relatively strong negative relationship but not a perfect one.
Therefore, while we can expect the predicted value to be reasonably close to the actual value due to the moderate negative correlation, we cannot be extremely confident that it will be exact. The prediction may have some degree of error as indicated by the correlation coefficient's value being less than -1 or closer to 1.
