6.If all the points in a scatter diagram lie on the least squares regression line, then the coefficient of correlation must be: 1.0 -1.0 either 1.0 or -1.0 0.0 b. A regression analysis between sales (in $1,000) and advertising (in $1,000) resulted in the following least square line: ý = 80 + 5x. This implies that: as advertising increases by $1,000, sales increases by $5,000. as advertising increases by $1,000, sales increases by $80,000. as advertising increases by $5, sales...
