3. What is the correlation coefficient for the set of data? Round your answer to the nearest thousandth.
0.014
0.989
0.075
4. About how tall would you expect one of these trees to be after 22 years?
22.31 ft.
35.2 ft.
44.25 ft.
46.2 ft.
5. 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. How confident can you be that your
predicted value will be reasonably close to the actual value?
I can’t be confident at all; this is about as close to a random guess as you can get.
I can be a little confident; it might be close, or it might be way off.
I can be very confident; it will be close, but it probably won’t be exact.
I can be certain that my predicted value will match the actual value exactly.
If you are doing Scatter Plots and Regression Lines Quick Check its
1-B.negative correlation
2-D.no correlation
3-B.0.989
4-C.44.25 ft
5-C.I can be very confident; it will be close, but it probably won’t be exact
if im wrong then i would like to hear why yours might be different than mine
not all are same
if you saying thx.
No Problem
Yes thank you, everyone, for the answers its

"am i right? or not hmmmm?" is correct for Unit 6 lesson 8 Scatter Plots and Regression Lines. Thank you so much for the help! :)
That's so helpful -_-
Like you can't imagine
