1:25:14 Le Ba where FE stands for the food expenditure of the ith household (in $), and inc; stands for the weekly income of the ith household (in $100), and e; is the error term. Aff regression using 40 observations, we obtain the estimated model as follows. FE = 83.42 + 10.21 . inc, (43.41) (2.09) here the numbers in parentheses are the corresponding standard errors. Calculat e 95% prediction interval for household with income $2000. Note that inc = do - 89.52, where inc stands for the average household income of the datas d o is the estimated standard error of the error term.
