Is this sample size practical? OA No, because the sample size is excessively large to be practical for most applications. O B. No, because the sample size should be as small as possible for most applications. OC. Yes, because the sample size should be as large as possible for most applications. O D. Yes, because the sample size is small enough to be practical for most applications.
