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 your intermediate calculations to 4 decimal places and final answers to 2 decimal places.)

Find the predicted value for y if x equals 12, 17, and 22. (Round intermediate coefficient values and final answers to 2 decimal places.)

Solution

(b) b1=0.60

b0=21.93

(c)  If x = 12, yhat= 29.13

If x = 17 , yhat =32.13

If x = 22, yhat = 35.13
