Question

Pick one of the options below and explain your answer?

Very confident
Somewhat confident
Not confident

Answer 1

very confident because a correlation coefficient of 1 is perfect then a correlation coefficient of .96 means it is like 96% accurate

Answer 2

Answer:

Very confident

Step-by-step explanation:

The closer the correlation coefficient is to 1, the stronger the correlation.  Anything above .4 is relatively strong.    So I would be very confident.
