The following data was collected to explore how the number of square feet in a house, the number of bedrooms, and the age of the house affect the selling price of the house. The dependent variable is the selling price of the house, the first independent variable (x1) is the square footage, the second independent variable (x2) is the number of bedrooms, and the third independent variable (x3) is the age of the house.

Step 1 of 2 :  

Find the p-value for the regression equation that fits the given data. Round your answer to four decimal places.

Step 2 of 2:

Determine if a statistically significant linear relationship exists between the independent and dependent variables at the 0.05 level of significance. If the relationship is statistically significant, identify the multiple regression equation that best fits the data, rounding the answers to three decimal places. Otherwise, indicate that there is not enough evidence to show that the relationship is statistically significant.

Solutions

Expert Solution

The statistical software output for this problem is:

From above output:

Step - 1: p - Value = 0.6051

Step - 2: Since p - value is greater than 0.05, we fail to reject Ho and hence, the equation is not significant. So,

There is not enough evidence to show that the relationship is statistically significant.
