Step-by-step explanation:
The formula to find the sample size is given by :-
, where p is the prior estimate of population proportion.
= Two-tailed z-value for (significance level).
E= Margin of error .
Given : Margin of error = 0.03
Confidence level = 90%=0.90
By z-value table :
a) The president's political advisors estimated the proportion supporting the current policy to be : p= 0.06.
Required sample size :
∴ Required sample size = 170
b) If no prior estimate of population proportion is given , then we assume
p= 0.5
Required sample size :
∴ Required sample size = 752
Of means times
86%=.86
