Short Answer

Use the following information for questions:
The next two questions are based on a regression equation for 55 college students withx = left forearm length (cm) and y = height. The forearm lengths ranged from 22 cm to 31 cm. The regression equation is $\hat{y}$ = 30.3 + 1.49x.
-The total sum of squares (SSTO) = 1054.8, and the error sum of squares (SSE) = 464.5. What is the value of r², the proportion of variation in y explained by its linear relationship with x?
