Question

In April 2015 the acting head of Eskom suggested that to improve its financial situation, Eskom should supply electricity directly to all customers. If this happened, many municipalities would lose the income they receive from the sale of electricity.

The table below shows the average percentage income received by municipalities from the sale of electricity per province for 2015 and 2014.

TABLE 2: AVERAGE PERCENTAGE INCOME RECEIVED BY MUNICIPALITIES PER PROVINCE FOR 2015 AND 2014

PROVINCE					AVERAGE PERCENTAGE INCOME

2015				2014
Eastern Cape		EC	20.6			34.0
Free State		FS	24.6			38.3
Gauteng			GP	30.2			29.4
KwaZulu-Natal	KZN	31.1			37.5
Limpopo			LP	21.3			20.6
Mpumalanga		MP	26.4			34.0
North West		NW	24.0			38.7
Northern Cape	NC	19.5			19.5
Western Cape	WC	31.1			44.8
A = 19,5% more than the average percentage income of the following year.

[Adapted from financial census of municipalities]

Use the table above to answer the following questions.

5.1.1 Arrange, in descending order, the average percentage incomes for 2015.

5.1.2 List ALL the provinces where the municipalities have an average percentage income greater than the mean percentage income for all the provinces during 2015.

5.1.3 Use the information in TABLE 2 to complete the bar graph on the grid provided on the ANSWER SHEET.

5.1.4 Determine the probability (as a percentage) of randomly choosing a municipality whose average percentage income for 2014 is not more than 35%.
