Let us say Sixto and a group of his classmates would want to study the consumption patterns of a municipality which has a population of 10,000 families. They would like to draw 1,000 sample units from this population. The clerk from the municipal hall provided them with the following information: 500 families belong to the highincome group; 2,500 families to the middle-income group; and 7,000 families to the lowincome group. Based on this information, how can Sixto and his friends pick 1,000 sample units proportionate to the aforementioned income classication? Demonstrate your sample distribution by constructing a table. Use MS Excel/Google Sheets formula for your calculations
