You use a line best fit for a set of data to make a prediction about an unknown value. the correlation coefficient for your data set is -0.993. how confident can you be that your predicted value will be reasonably close to the actual value? a. i can't be confident at all; this is about as close to a random guess you could get b. i can be a little confident; it might be close, or it might by way off c. i can be very confident; it will be close, but it probably won't be exact d. i can be certain that my predicted value will match the actual value exactly i think it's c, but i'm not so sure. : )
