A regression line was calculated as y = 9.7 - 3.2x. What is the slope of this line?
\n" ); document.write( "slope = -3.2
\n" ); document.write( "---------------------------
\n" ); document.write( "The equation of a regression line is y=4.6 +3.2x.Find the y intercept of this line.
\n" ); document.write( "intercept = 4.6
\n" ); document.write( "--------------------------
\n" ); document.write( "If the correlation coefficient r is equal to .53, find the coefficient of determination
\n" ); document.write( "R^2 = 0.2809
\n" ); document.write( "------------------------------
\n" ); document.write( " and the coefficient f nondetermination
\n" ); document.write( "1-R^2 = 0.7191
\n" ); document.write( "============================================
