RISI (this question is tricky) Assume there are only three income groups, $45,000, $60,000, and $125,000 in a given city. There are 5 districts in the city, A, B, C, D, and E. Details are provided in the Table below. 1) What are the median incomes in each district and in the city as a whole? 2) Which districts are predominantly poor and predominantly rich, respectively? 3) Calculate the RISI (report 4 decimals, e.g., RISI=1.2345)
