It is expected that earnings per hour (wage) depends on years of education (educ), years of experience (exper) and a dummy variable metro which is equal to 1 for workers who live in a metropolitan area and 0 for workers who live outside a metropolitan area. use the data in q1 data for this question. [1] plot wage against educ, exper and metro. estimate the following regression model wage=β_0+β_1 educ β_2 exper+β_3 metro+u report your fitted results with relevant computer output. check the regression assumptions and explain any possible problems you identify. interpret the regression coefficients
