Answer:
The size of the sample needed = 67.65
Explanation:
Given that :
The margin of error = 10% = 0.10
The confidence level = 90% = 0.90
Level of significance = 1 - 0.90 = 0.10
At ∝ = 0.10

Since the proportion of people that supported him/her is not given, we assumed p = 0.50
The margin of error formula can be expressed as:


Squaring both sides; we have:



n = 67.65
Therefore, the required sample size = 67.65
