Y, whereas price and household income are the

Step 3: Click “Regression”
Click “Regression” and then “OK.”
Step 4: Define input ranges in Excel
Select C2 to C7 into “Input Y Range” and A2 to B7 into “Input X Range.” Then click “OK.”
Step 5: Interpret Excel output
We can see 𝑏₀ = 6.73, 𝑏₁ = -0.45, and b2 =0.35. We can write the estimated regression function below. However, note that all the p-value for both Xs (i.e., 0.2398 and 0.2748) are greater than 0.05, and thus these two predictors, price and household income, are not statistically significant.
