-
A real estate agent uses a simple regression model to estimate the value of a home based on square size in which Y is the value of the home in dollars and X is the size in total square feet. The regression
ˆ
equation is Y(hat) = 253000 + 438 X .-
Interpret the slope using the units of the problem.
-

Rhonda Clark, a Slippery Rock, Pennsylvania, real estate developer, has devised a regression model to help determine residential housing prices in northwestern Pennsylvania. The model was developed using recent sales in a particular neighborhood. The price (Y) of the house is based on the size (square footage = X) of the house. The model is: Y=13,473+37.65XY=13,473+37.65X The coefficient of correlation for the model is 0.63. Use the model to predict the selling price of a house that is 1,860 square...

Which of the following statements is true with respect to a simple linear regression model? a. The regression slope coefficient is the square of the correlation coefficient b. It is possible that the correlation between a y and x variable might be statistically significant, but the regression slope coefficient could be determined to be zero since they measure different things c. The percentage of variation in the dependent variable that is explained by the independent variable can be determined by...

A real estate analyst has developed a multiple regression line, y = 60 + 0.068 x1 – 2.5 x2, to predict the market price of a home (in $1,000s), using two independent variables, x1 = the total number of square feet of living space, and x2 = the age of the house in years. With this regression model, what is the predicted price of a 10-year old home with 2,500 square feet of living space? Dependent / Response Variable Independent...
