Answer:
n = 43 samples
Step-by-step explanation:
Error margin, E = 0.15
Confidence Interval, CI = 95% = 0.95
Significance level, α = 1 - 0.95
α = 0.05
α/2 = 0.025
To calculate population proportion, the sample size formula is:
n = 0.25 [(Zα/2) /E]²
Zα/2 = Z₀.₀₂₅ = 1.96
n = 0.25 * [(Z₀.₀₂₅)/E]²
n = 0.25 * [1.96/0.15]²
n = 42.68
n = 43 samples
