760

820

690
What is the correlation coefficient for the data, and what does it represent?

Answer 1

0; It represents no correlation between x and y
0.999; Represents a linear positive correlation between x and y
-0.999; represents a negative correlation between x and y
0.999; it represents a negative correlation between x and y

Answer 2

@phi HELP

Answer 3

It would seem to have a negative correlation I think so would that leave us with C and D?

Answer 4

D (unless it's a typo) does not have a negative sign, so though it says negative, the number is not negative and that is not correct.

Answer 5

as x grows, y gets smaller
that is a negative correlation.
if you plot the points as an x-y pair you get a straight line (so close to perfect negative correlation)

Answer 6

So C?
