Proportion is a mathematical comparison of two numbers. If two sets of provided numbers increase or decrease in the same ratio, the ratios are thought to be directly proportional with one another. Proportions are represented by the symbols "::" or "=".
The formula was:
n = [(z-value^2 x p x q)]/E^2
n = sample size
z-value will be 2.58 as per z-table to represent the 99% confidence interval,
p and q values will be 5 as they have not mentioned any
E = 0.04^2 .
n=2.58^2 x5x5/0.04^2
=6.656x25/0.0016
=166.4/0.0016
=0.26624
