Answer #1
  • Answer is B
    B.

    the population standard deviation


Explanation: To get sample size necessary to estimate a population proportion we use formula of margin of error that is given by

where

  • is can be calculated using level of confidence
  • p* is estimate of true population proportion
  • Margin of error is the error tha can be tolerated

So we can see we are not using population standard deviation anywhere so B is the answer
