Question 934822: ____The correlation coefficient between the hours that a peron is awake during a 24-hour period and the hours that same person is asleep during a 24-hour period is most likely to be
A)Near 0 ; B)Near -0.8 ; C)Near +0.8 ; D)Exactly -1.0 ; E)Exactly +1.0
x = # of hours person is awake
y = # of hours person is asleep
then we know that x+y = 24 which turns into y = -x + 24.
We have a perfect linear correlation going on here which means r = -1.0.
The value of r is negative to reflect the fact we have a negative slope.

You can put this solution on YOUR website!
if is the number of hours you sleep and is the number of hours you're awake, and are related exactly by a linear equation with a negative slope
so, or where a slope is
