Assume that he ample in amimple rendom aample obtained from a nomally distributed populetion of 1Q scores of statistice professors. Use the table below to find the minimum sample size needed to be 90% confident that the smp andard devintiona within 20% ofe. la hia ample sie practical? To be 95% confident that le thin the vale of e, the aample elre 10.2os 788 nahould be at lonst To be 90% confident that ale within of the value o o, the sample size nahould be at least 5% 10% 20% 30% 40% 50% 192 48 21 12 1% 5% 10% 20% 30% 40% 50% 33,218 1,336 336 22 14 The minimum sample size needed is 55. 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.

Assume that the nample in a simple rendom aample obtained from a normally distributed populetion of IQ scores of statistics professors. Use the table below to find the minimum sample siza needed to be 99% confident that the samp atendared devintion a is within 20% of a. la this mample size practical? To be 05% confident that le thin of the vahue of e, the eample atre should be at lonst To be DO% confident thata le within of the value of 6, the eample alro b3.218 1,336 n should be at loast 1% 10% 20% 30% 40% 50% 5% 10,205 768 102 48 21 12 1% 5% 10% 20% 30% 40% 50% 336 85 38 22 14 The minimum sample size neoded is 55. Is this sample size practical? O A 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. Yos, bocause the sample size is small enough to be practical for most applications.
