Question

Find the minimum sample size required to estimate the population
proportion

Confidence level:99%

E: 9/100

p^ and q^ are unknown

Answer #1

We have given,

Preliminary estimate for proportion (Not Known) = 0.5

Margin of error =E=0.09

Level of significance = 1-0.99=0.01

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

Sample size formula is

=204.81
