O A. Yes. because the sample size is small enough to be practical for most applications. 0 B. Yes. because the sample size should be as large as possible for most applications 0 C. No, because the sample size is excessively large to be pradical for most applications. 0 D. No, because the sample size should be as small as possible for most applications
