Use the table below to find the minimum sample size needed to be 95% confident that the sample standard deviation s is within 20% of o. Is this sample size practical? To be 95% confident that's is within 1% 5% 10% 20% 30% 40% 50% of the value of o, the sample size 48 n should be at least 19,205 768 192 21 To be 99% confident that's is 1% 5% within 10% 20% 30% 40% 50% of the value of o, the sample size n should be at least 33,218 1,336 336 38 14 The minimum sample size needed is Is this sample size practical? A. No, because the sample size is excessively large to be practical for most applications. OB. Yes, because the sample size is small enough to be practical for most applications. C. Yes, because the sample size should be as large as possible for most applications. D. No, because the sample size should be as small as possible for most applications.
