You run a simple linear regression of high school dropout rates (0100%) as a unction of school expenditure per student (\$) and obtain an intercept estimate b0= 37.5. In words, what does the intercept estimate represent? If the school expenditure per student were $0, our model predicts that the dropout rate would be 87.5% All of the above A one unit increase in expenditures per student is associated with a 87.5% increase in the dropout rate There is a weak positive association between dropout rates and school expenditures
