s = 6143 R-sq = 477% R-sq(adj) = 448%

 

Can you tell me what is the equation of the least squares regression line that would be used to predict musical aptitude from an IQ score and a 95% confidence interval for the slope of the regression line?

 

Can we conclude that there is a significant relationship between IQ score and musical aptitude at? = 005?

 

What does this value of s= 6143 in the context of the problem?
