6 14 5 10

Use regression to find the equation for the line of best fit. (Round your answers to three decimal places.)
ŷ = +   x

Homework Answers

Answer #1

To calculate the regression equation for the given sample details the following table calculation is made as:

Based on the table calculation following is calculated as:

So,  based on the above calculations, the regression coefficients (the slope m, and the y-intercept n) is calculated as:

So, the regression equation is computed as:

Y=2.196+1.795X
