We develоp а regressiоn mоdel to predict the аssessed vаlue of houses, using the size of the houses (in square feet) and the age of the houses (in years). Below, we observe partial results of running a multiple regression: Multiple R 0.909120107           R Square 0.826499369           Adjusted R Square 0.797582598           Standard Error 2168.165527           Observations 15                         ANOVA               df SS MS F     Regression 2 268724699 134362349.5 28.58200688     Residual 12 56411301.01 4700941.751       Total 14 325136000                         Coefficients Standard Error t Stat P-value Upper 95% Lower 95.0% Intercept 163775.1236 5407.173152 30.28849253 1.05104E-12 175556.3418 151993.9054 Size 10.72518298 3.014327189 3.558068619 0.003937797 17.29283773 4.157528235 Age -284.254348 83.59835914 -3.400238365 0.005267391 -102.1091708 -466.3995252 Provide the proper interpretation for the slope of the size of houses (m1{"version":"1.1","math":"m1"}).
