The calculation for required sample size will be as follows:

z = 1.96 (corresponding to a 95% confidence level)

p = 0.5

q= 1-0.5= 0.5

e = 0.05

Thus, the result shows that a sample size of approximately 384
individuals to estimate the proportion of people supporting the
political candidate in the city.

At 99 percent confidence level with ±5 percent precision, the
calculation for required sample size will be as follows-

z = 2.58 (corresponding to a 99% confidence level)

p = 0.5

q = 1-0.5= 0.5

e = 0.05
