x 5.75 6.00 6.75 7.25 7.50

y 61 41 62 81 98

r=0.855

x-bar=6.65

~y68.6

y=-93.145+24-323x

what percentage of the variation in y cannot be explained by the corresponding variation in x and the least-squares line?

(Points: 4)

**MathGuru**, Sunday, August 22, 2010 at 8:14amYou wish to find the coefficient of nondetermination, which is the percentage of the variation in y that cannot be explained by the corresponding variation in x.

Formula: 1 - r^2

I'll let you take it from here. Convert the decimal to a percentage for your answer.
