Question

Real Estate Agents from Coldwell Banker are interested in using land area to predict the selling price of the corresponding house. R-sq = R-Sq (adj) = 46041.0 14.6% 14.3% SE Coef PredictorCoef Constant 136157 22.71 0.000 Land Area 45.212 6.599 6.85 0.000 Using the MiniTab output above, determine the expression for the line of best fit LandArea = 45.212 + 136157 * SellingPrice SellingPrice = 45.212 + 136157 * LandArea SellingPrice = 136157 + 45.212 * LandArea LandArea 136157 + 45.212 * SellingPrice

Explanation / Answer

Ans:

Line of best fit or regression equation:

y'=a+bx

where,

b=slope

a=y-intercept

x is the perdictor i.e. land area and y is the response variable i.e. selling price.

slope cofficient from above table is,b=45.212

y-intercept,a=136157

Hence,line of best fit will be:

Selling price=136157+45.212*landArea

Third Option is correct.
