Question 5
a)
Suppose P(A) represents the probability that a local authority in Namibia will allocate
more resources to poverty alleviation programmes in the year 2025. If P(A) = 0.65, what
is the probability that the local authority will not allocate more resources to poverty
alleviation programmes in the year 2025?
(2)
b)
The following show the marks obtained by selected Namibian spatial planners in an
aptitude test: 22, 68, 77, 33, 50, 60, 60, 55, 65 and 70. Calculate the following for the
marks:
(i) Mean
(2)
(ii) Median
(2)
(iii) Mode
(1)
(iv) Range

[9]
Question 6
A survey estimates that the probability of the planning process serving the public interest is 0.74. For
the planning processes which serve the public interest, 45% also promote private sector principles of
efficient decision-making. What is the probability that a randomly selected planning process both
serves the public interest and promotes private sector principles of efficient decision-making?
[2]
Question 7
Let Y represent the number of times planners have organized stakeholder consultations over the past
year. Assuming that the probability distribution of Y is approximately: P(0) =0.15, P(l) =0.30, P(2) =
0.22, P(3) = 0.28 and P(4) = 0.05.
a) Is Ya discrete or a continuous variable? Pleaseexplain briefly.
(2)
b) Construct a table showing the probability distribution of V.
(4)
c) Find the mean of the probability distribution.

affordable housing. Explain how you would proceed if you want a systematic random sample of 400
residents.
