Question

The data below show the selling price, square footage, bedrooms, and age of houses that have sold in a neighborhood in the last six months. Develop seven regression models as below using the corresponding Excel data. (Model 1) Y = selling price, X_1 = square footage (House Selling Price Model 1 Data) (Model 2) Y = selling price, X_2 = bedrooms (House Selling Price Model 2 Data) (Model 3) Y = selling price, X_3 = age (House Selling Price Model 3 Data) (Model 4) Y = selling price, X_1 = square footage, X_2 = bedrooms (House Selling Price Model 4 Data) (Model 5) Y = selling price, X_1 = square footage, X_3 = age (House Selling Price Model 5 Data) (Model 6) Y = selling price, X_2 = bedrooms, X_3 = age (House Selling Price Model 6 Data) (Model 7) Y = selling price, X_1 = square footage, X_2 = bedrooms, X_3 = age (House Selling Price Model 7 Data) (House Selling Price) Find the p values of the seven regression models How many regressions models are significant with alpha = 0.05? A. 2 B. 1 C. 5 D. 4 E. 7 F. 3 G. 6 (House Selling Price) The data below show the selling price, square footage bedrooms, and age of houses that have sold in a neighborhood in the last six months.

How many of the three simple regression models show a negative relationship between the dependent A. 2 B. 1 C. 3 D. 0

Explanation / Answer

1) how many regression model are significant with alpha = 0.05

correct answer is 6

option G) is correct

p-value is greater than 0.05 for X3 only

2) how many of simple regression model shows negative relationship

correct answer is 3

option C) 3 is correct

X1 - b1 = -0.00032

X2 - b1 = -0.01301

X3 - b1 = -10.2857

If you want excel file ,i will share ,please comment as i have answered your other question too ,it would be better if you can excel file only.
