Suppose the total monetary value of sales on N = 5500 invoices is R1 500 000 and that a number of invoices must be selected according to a probability proportional to size (PPS) selection process. Suppose we determine that n = 15 invoices are to be selected.

Gestel die totale monetêre waarde van verkope van N = 5500 fakture is R1 500 000 en dat ʼn aantal fakture volgens ʼn waarskynlikheid ewekansig aan grootte (WEG) seleksie-proses getrek moet word. Gestel ons bepaal dat n = 15 fakture geselekteer moet word.

Suppose the first six 7-digit numbers are 0005410, 0013247, 0013522, 0020115, 0020719, and 0027469. Given the information above, complete the table and indicate which invoices will be included in the sample.
