Which of the following is not necessary to determine the size of a sample of a population?
a. size of the population
b. the level of confidence in the estimation of the population
parameter
c. an estimate of the variation of the population
d. the maximum error allowed in the estimation of the population
parameter
Homework Answers
as sample size required n =(z/margin of error)2*std deviation ; therefore it depends upon level of confidence ; variance and maximum error allowed.
