In an investigation of three banks in South Africa, ten analysts were asked to indicate the risk of one of the banks to become insolvent as ‘low’, ‘medium’ or ‘high’. The following excerpt from the data is given to you. From this we can, for example, see the evaluation of Bank 1 was allocated to analysts 1, 2, 8, and 10 and that analyst 8 deemed the risk to be low, while the other three deemed it to be high.

In ’n ondersoek van drie banke in Suid-Afrika is tien analiste gevra om een van die banke se risiko om insolvent te raak, as ‘laag’, ‘medium’ of ‘hoog’ aan te dui. Die volgende uittreksel uit die data word aan u gegee. Hieruit kan ons byvoorbeeld sien dat die evaluering van Bank 1 aan analiste 1, 2, 8 en 10 toegeken is, en dat analis 8 die risiko as laag beskou het, terwyl die ander drie die risiko as hoog beskou het.

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.

If the PPS selection method is used to choose invoices from this population, calculate the probability that Invoice 7 is the first invoice selected. Assume that the random numbers are not ordered from smallest to largest.

/

Indien die WEG seleksie-proses gebruik word om fakture uit hierdie populasie te selekteer, bereken die waarskynlikheid dat Faktuur 7 eerste geselekteer word. Neem aan dat die ewekansige getalle nie van klein na groot gerangskik word nie.
