Question

The following table was generated from the sample data of 10 10 newborn babies regarding the weight of the mother at birth, the weight of the father at birth, and the weight of the baby at birth. The dependent variable is the weight of the baby, the first independent variable (x 1 ) is the mother's weight, and the second independent variable (x 2 ) is the father's weight.

Step 1 of 2: Write the multiple regression equation for the computer output given. Round your answers to three decimal places.

Step 2 of 2:Indicate if any of the independent variables could be eliminated at the 0.05 level of significance.

Coefficients Standard Error t-Stat p-value Intercept 4.325000 4.289186 1.008350 0.352207 Mother's Weight 1.091667 0.284780 3.833371 0.008625 Father's Weight 0.391667 0.480439 0.815226 0.446088

Explanation / Answer

Step - 1: from the output the multiple regression equation will be:

y = -4.325 + 1.092 x1 + 0.392 x2

Step - 2: Yes father's weight could be eliminated because the P value associated with it is greater than 0.05 and hence x2 is not a significant variable.
