<PRE><B>Question 1120131</B>
there is not enough information to solve this problem without making certain assumptions
:
if you were given the standard deviation of the population, it is solvable
:
assume the population is large, say 100,000 and the proportion is 50% of the population supports the candidate
:
then the formula for sample sizing using the proportion formula yields an answer of 188
:
note that the sample size does not increase appreciably with populations greater than 100,000
