SAMPLE REGRESSION COEFFICIENT OF X ON Y IS COUNTING BY THE FORMULA Select one: (overline (xy)-overline (x)cdot overline (y))/(sigma _(y)^2) (overline (xy)-overline (x)cdot overline (y))/(sigma _(x)^2) (bar (x)^2cdot bar (y)-bar (x)cdot bar (x))/(sigma _(x)^2) (bar (y^2)cdot bar (x)-bar (y)cdot bar (y))/(sigma _(y)^2) (overline (xy)-overline (x)cdot overline (y))/(sigma _(y)sigma _(x))

The correct answer is: Explanation:The sample regression coefficient of X on Y, also known as the slope of the regression line, is calculated using the formula: Where:- is the mean of the product of X and Y- is the mean of X- is the mean of Y- is the standard deviation of Y- is the standard deviation of XThis formula represents the ratio of the covariance of X and Y to the product of their standard deviations, which gives the slope of the regression line.The other options provided are incorrect formulas for calculating the sample regression coefficient of X on Y.
