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

The cook corporation has two divisions--east and west. the divisions have the following revenues and expenses: east westsales $ 603,000 $ 506,000 variable costs 231,000 300,000 traceable fixed costs 151,500 192,000 allocated common corporate costs 128,600 156,000 net operating income (loss) $ 91,900 $ (142,000 )the management of cook is considering the elimination of the west division. if the west division were eliminated, its traceable fixed costs could be avoided. total common corporate costs would be unaffected by this decision. given these data, the elimination of the west division would result in an overall company net operating income (loss) of: multiple choice$91,900$(64,100)$(142,000)$(5 0,100)
