Use the table below to find the minimum sample size needed to be 99% confident that the sample standard deviation s is within 40% 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 19 205 768 192 48 21 12 8 n should be at least To be 99% confident that s is within 1% 5% 10% 20% 30% 40% 50% of the value of o, the sample size 33,218 1,336 336 85 38 22 14 in should be at least The minimum sample size needed is Is this sample size practical? O A. Yes, because the sample size is small enough to be practical for most applications O B. Yes, because the sample size should be as large as possible for most applications O C. No, because the sample size is excessively large to be practical for most applications OD.
