「ソ」の標準偏差の求め方について質問です。 「ソ」は標本比率の標準偏差なので公式√n/1p(1-p)で求めれると思ったのですが、解説では新たにSを置いて解いています。なぜでしょうか？

(3)今年度の h≧4である高校生の母比率が昨年度の0.4と異 なるといえるかを, 有意水準5%で仮説検定する。 帰無仮説を 「p=0.4」, 対立仮説を 「p≠0.4」 とする. (X) (2)-( 11 帰無仮説が正しいとする. 母比率=0.4の母集団から, 標本 の大きさ n=1600 の無作為標本を抽出したとき, 4 である 高校生の人数を表す確率変数をSとすると、Sは二項分布 B (1600, 0.4) に従うから, Sの平均 E(S) と標準偏差 o (S)は E(S)=1600 × 0.4 = 640, o(S)=√1600×0.4×(1-0.4)=8√6 S. である. ここで, h≧4 である高校生の標本比率は R= 1600 であるから E(R)= E(S) 640 = =0.4, 1600 1600 defensesσ(R) = 6(S) 8/6 √6 = 1600 1600 200 Seas である. n=1600 は十分に大きいので,Rは近似的に平均 3863X3 1.お 8 0.4 1 ,標準偏差 6 の正規分布に従う. よっ 200 まして、確率変数 R-0.4 は近似的に標準正規分布N (0, 1) に従 √√6 (1.0,004) Y 200 に従う 布N(G う. 正規分布表により R-0.4 - 1.96 ≦ ≤1.96 √6 200 21 (763 =(1.0-1)×1.0×00

Long-s doctrin holds that we are protected from fungi not just by layered immune defenses but ( e ) we are mammals*, with core temperatures higher than fungi prefer. The cooler outer surfaces of our bodies are at risk of minor assaults-think of athlete's foot*, yeast infections, ringworm*-but in people with healthy immune systems, invasive* infections have been ( f ). That may have left us overconfident. "We have an enormous (g) spot," says Arturo Casadevall, a physician and molecular microbiologist at the Johns Hopkins Bloomberg School of Public Health. "Walk into the street and ask people what are they afraid of, and they'll tell you they're afraid of bacteria, they're afraid of viruses, but they don't fear dying of fungi." Ironically, it is our successes that made us vulnerable*. Fungi exploit damaged immune systems, but before the mid-20th century people with impaired immunity didn't live very long. Since then, medicine has gotten very good at keeping such people (h), even though their immune systems are compromised by illness or cancer treatment or age. It has also developed an array of therapies that deliberately suppress immunity, to keep transplant recipients healthy and treat autoimmune* disorders such as lupus* and rheumatoid arthritis*. ( i ) vast numbers of people are living now who are especially vulnerable to fungi. Not all of our vulnerability is the fault of medicine preserving life so successfully. Other ( j ) actions have opened more doors between the fungal world and our own. We clear land for crops and settlement and perturb* what were stable balances between fungi and their hosts. We carry goods and animals across the world, and fungi hitchhike on them. We drench crops in fungicides* and enhance the resistance of organisms residing nearby. (s) ELSE

テーマ 専門性☆☆☆ 英文レベル★★★ 30 DNAはウイルスから? 文 11 What with the threat of bird flu, the reality of HIV, and the genera unseemliness of having one's cells pressed into labour on behalf of something alien and microscopic, it is small wonder that people don't much like viruses. But we may actually have something to thank the little 5 parasites for. They may have been the first creatures to find a use for DNA, a discovery that set life on the road to its current rich complexity 12 The origin of the double helix is a more complicated issue than it might at first seem. DNA's ubiquity -all cells use it to store their genomes - suggests it has been around since the earliest days of life 10 but when exactly did the double spiral of bases first appear? Some think it was after cells and proteins had been around for a while. Others say DNA showed up before cell membranes had even been invented/ The fact that different sorts of cell make and copy the molecule in very different ways has led others to suggest that the charms of the double 15 helix might have been discovered more than once. And all these ideas have drawbacks. "To my knowledge, up to now there has been no ⚫ convincing story of how DNA originated," says evolutionary biologist Patrick Forterre of the University of Paris-Sud, Orsay. 13 Forterre claims to have a solution. Viruses, he thinks, invented » DNA as a way the defences of the cells they infected. Little more than packets of genetic material, viruses are notoriously adept at* avoiding detection, as influenza's annual self-reinvention attests. Forterre argues that viruses were up to similar tricks when life was young, and that DNA was one of their innovations. To some researchers 25 the idea is an appealing way to fill in a chunk of the DNA puzzle. 270 •
