Answer:
The sample size n = 4225
Step-by-step explanation:
We will use maximum error formula =
but we will find sample size "n"
Squaring on both sides , we get
Given 99% confidence interval (z value) = 2.56
given maximum error = 0.02
n≤ ( here S.D = p(1-p) ≤ 1/2
on simplification , we get n = 4225
<u>Conclusion</u>:
The sample size of two samples is n = 4225
<u>verification</u>:-
We will use maximum error formula = =
= 0.0196
substitute all values and simplify we get maximum error is 0.02
