Asked by SAM

you use a line of 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 as you can get
b. I can be a little confident; it might be close, or it may be 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*****
