The sample size to meet the error margin is 2185.
What is the error margin?
The margin of error is a statistic that describes how much random sampling error there is in survey results. One should have less faith that a poll's findings would accurately reflect those of a population census the higher the margin of error.
Here, we have
The sample size (n) is calculated according to the formula:
n = p(1 - p) (z²/ e²)
Where:
z = 1.96 for a confidence level (α) of 95%, p = proportion, e = margin of error.
z = 1.96, p = 0.35, e = 0.02
n = 0.35(1 - 0.35) (1.962/ 0.022)
n = (0.2275)(9604)
= 2184.91
n ≈ 2185
Hence, the sample size meets the error margin is 2185.
