Question

Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. The table shows the shoe size and heights (in.) for 6 men Shoe size, x Height 7.5 65.5 9.5 69.5 11.0 71.5 11.5 72.5 13.0 73.5 13.5 72.5 Find the regression equation (Round to three decimal places as needed.) Choose the correct graph below 75 6 14 14 14 Shoe size Shoe size Shoe size Shoe size

Answer 1

Solution :

Given that x as 7.5 , 9.5 , 11.0 , 11.5 , 13.0 , 13.5

y as 65.5, 69.5, 71.5 , 72.5 , 73.5 , 72.5

=> The equation of the regression line is y^ = 1.240*x + 57.193

=> Option C. graph
