The required sample size is
(Round up to the nearest whole number as needed.)
Does the sample size seem practical?
O A. Yes, because the required sample size is a fairly large number.
O B. No, because the required sample size is a fairly small number.
OC. Yes, because the required sample size is a fairly small number.
O D. No, because the required sample size is a fairly large number.
