Savings and income Your microeconomics professor gives you a dataset of 90 households that describes the savings behavior and economic characteristics (income, famsize) of a sample of families in South Bend. The dataset also contains demographic information about the head of household (age, educ). She asks you to investigate the relationship between savings and family income (both measured in USD). You estimate the following population model for households h. Savings,= Bo + BincomeIncomer + Bogeagen + Bagezagen + Beseduch + Befamsizen + un The output from your investigation is below (some of the STATA output is omitted for the purposes of this question): Regression 2 reg savings income age age2 educ size Source | Model | 74947229.8 Residual I 870066450 Total 945013680 savings I income I SS df .0198167 age | -261.5792 age2 | 3.947223 educ | 240.4716 size 127.6799 cons 1 2111.449 Coef.
