Calculate b1 and b0 What is the sample regression equation N

Calculate b₁ and b₀. What is the sample regression equation? (Negative values should be indicated by a minus sign. Round intermediate calculations to 4 decimal places and final answers to 2 decimal places.)

Find the predicted value for y if x equals 25, 104 and 226. (Round intermediate coefficient values and final answers to 2 decimal places.)

Consider the following sample data:

Sol)

The Regression equation is Y=a+bX

From the Excel

From above we hve

intercept bo=-58

Slope=7

Hence predicted Regression is

Y hat= -58+ 7x

c) If x = 25 then Yhat =117

If x = 104 then Yhat =670

If x = 226 then Yhat 1524
