Question

Researchers at ICU seek to establish the influence of the (Pre- pregnancy Weights of Mothers) X, on the (Birth weights of their Infants) Y. The following linear regression model was computed. The correlation coefficient was found to be r= 0.5212. .  

Source	SS df                            MS
Model Residual	1406178.99                          1                     1406178.99 3769489.01                         23                    163890.826

Number of obs = 25

F (1,23)               =   8.58

Prob > F              =   0.0075

R- Squared         =   0.2717

Adj R- Squared =   0.2400
