Answer:
At least 653 citizens need to be sampled.
Step-by-step explanation:
The following formula is used to compute the minimum sample size required to estimate the true proportion who are in favor of gun control legislation within 5% margin of error:
n≥ p×(1-p) × where
- n is the sample size
- p is the sample proportion of people who are in favor of gun control legislation (
- z is the corresponding z-score for 99% confidence level (2.575)
- ME is the margin of error in the estimation (5% or 0.05)
Putting numbers in the formula
n≥ 0.5625×0.4375 × ≈652.7
n needs to be<em> at least 653</em> to provide this equation.
