[10 points] Data interpretation A group of researchers is interested in measuring the extent to which Brazilian immigrants in the US are positively or negatively selected in terms of educational attainment. To do so, they have compiled data on the educational attainment and age distribution of Brazilian immigrants in the US, as well on the educational attainment and age distribution of Brazilians who stayed in Brazil. Specically, they have data on whether individuals are "young" or l'old", and whether they have "low" or "high" educational attainment. The information they collected can be summarized in the following two tables: Table I Age distribution Table 2 Educational level Low education | High education | "Young" stayers 40% | 60% I "Old" stayers 60% 40% "Young" migrants 40% 60% "Old" migrants 60% | 40% | [5 points]. The researchers rst decide to compare migrants to stayers with respect to their educational attainment. However, they forget to age-standardize the data (as in Feliciano's article discussed in lecture). What would they conclude with respect to the educational selectivity of Brazilian migrants to the US? Is it negative, neutral, or positive
