Assume that the sample is a aimple random aample obtained fron a normaly distributed population of IQ scores of statistice profesnorn. Use the table below to find the minimum seample size needed to be 99% confident that the semple stendard deviation a is within 20% of a. Is this sample aire practioal? To be 95%G confident thata le tthin bt thhe vehue of a, the sample alze ka 20s 788 192 48 hshould be et lennt * to be 99% confident that s la 1% 10% 20% 30% 40% 50% 21 12 5% 10% 20% 30% 40% 50% 1% or the vakve of a. the sample elze n should be at lonst 33,218 1,336e 336 85 38 14 The minimum sample size noaded is. Is this sample size practical? OA No, becnuse the sample size is axcessively large to be practical for most applications. 2 B.
