Question

Use the given information to find the minimum sample size required to estimate the population proportion.

Margin of error: 0.028; confidence level: 99%; p and q unknown

Answer #1

We have given,

Preliminary estimate for proportion (Not Known) = 0.5

Margin of error =E=0.028

Level of significance = 1-0.99=0.01

Z critical value is (by using Z table) =2.576

Sample size =2116 |
