February 5, 2016, 9:10 11:00 am (1) For the subset making k or less: (cid:2020)(cid:3025)(cid:3364)=(cid:1831)(cid:4670)(cid:1850)(cid:3364)(cid:4671)=(cid:2020)=. 3419(cid:1837) (cid:2026)(cid:3025)(cid:3364)=(cid:1845)(cid:1830)(cid:4670)(cid:1850)(cid:3364)(cid:4671)= (cid:2026) (cid:1866)=29. 96436. 2000 =sh. 670(cid:1837) sampling distribution of (cid:1850)(cid:3364) will be normal even. A sample size of 2,000 is surely sufficiently large such that the central limit theorem (clt) applies: the though the population is extremely positively skewed. For the full population: (cid:2020)(cid:3025)(cid:3364)=(cid:1831)(cid:4670)(cid:1850)(cid:3364)(cid:4671)=(cid:2020)=. 1793(cid:1837) (cid:2026)(cid:3025)(cid:3364)=(cid:1845)(cid:1830)(cid:4670)(cid:1850)(cid:3364)(cid:4671)= (cid:2026) (cid:1866)=37. 52571 sampling distribution of (cid:1850)(cid:3364) will be normal even though. A sample size of 2,000 is surely sufficiently large such that the central limit theorem (clt) applies: the the population is very extremely positively skewed. E[x-bar] = 125. 342, sd[x-bar] = 0. 670, n = 2000. E[x-bar] = 127. 179, sd[x-bar] = 0. 839, n = 2000 y t i s n e. While both are normal (n = 2,000 is surely sufficiently large), there are two differences in these sampling distributions. The second one (above) is centered about ,000 higher and is more spread out.
