留学先の統計学の問題です。 4、5、2問あります。 後、数時間で提出となり、焦っております。 どなたかお力添えをお願いします😭😭😭 時差があり、深夜回答はたいへんありがたいです。 朝までにお願いします。

4. The temperature of the Earth at different sites can be measured in two ways. One, by taking readings using thermometers on the ground (x), which is extremely tedious and time consuming. Second, bylasers positioned on satellites revolving about the Earth (v). which ie a less accurate method and may be biased. The readings for both are given below: Ground Therm., x Satellite Laser, y Site 1 4.6 4.7 2 17.3 19.5 3 12.2 12.5 4 3.6 4.2 5 6.2 6.0 6 14.8 15.4 7 11.4 14.9 8 14.9 17.8 emignaia 9 9.3 9.7 10 10.4 10.5 11 7.2 7.4 You would like to test the claim that the Laser method gives a significantly higher reading than the ground therm. method. You may assume that the difference between pairs of scores is approximately normal. A) Would testing for a difference in means or a paired difference test be better to use here? Why? B) Perform the test you concluded in part A). 200 seetV C) Would you have any reservations about yourinference? Why?

問題8についてです。解答はAになります。 AとCで解答を迷いました。Cが不適となる理由を教えてください。 Sがclimate、Vはcarriesであり、空欄には修飾句(形容詞句)、もしくは関係詞節(実質的な形容詞節としての働き)が入ると考えました。

流体力学の最初の最初、ラグランジュ微分のところでつまづいて困っております。 二枚目の？をつけた計算過程はどのような微分なのでしょうか？ よろしくお願いします。

の1 流れの運動学 8 1 = (u.V)u U のようにして得られた. 記号▽はナブラ (nabla) とよみ 0 鶏分(1.14) 0 マ= e』 + ey Oy 0z のように定義される演算子 (operator) であるす. ea, ey. Ez はそれぞれ』軸, 軸,2軸の正の向きに向かう単位ベクトル (unit vector) で, これらを基本ベク トル (fundamental unit vector)という。 式(1.12) の両辺を At でわって, At →0 の極限をとると,流体粒子の受け る加速度a(z,t) を求めることができ に Au a(x, t) = lim + (u-V) u(z, t) At→0 At Ot D -u(x,t) Dt となる.ただし D +u.V Ot Dt で,D/Dt をラグランジュ微分 (Lagrangian derivative),あるいは実質微 分(substantial derivative), あるいは物質微分 (material derivative) という。 Du/Dt= Ou/0t+ (u.V)uの右辺第1項は, 流体中のある点aをつぎつぎと 通過する流体粒子の速度の時間的変化の割合を表しており,局所加速度 (local acceleration) とよばれている. また第2項は,点cにある流体粒子がある瞬間 にその前後の流体粒子の速度差のために受ける速度の時間的変化割合で対流加 速度 (convective acceleration) とよばれている。 ラグランジュ微分 D/Dtは, オイラーの方法の意味で »とtの関数として表 された量,すなわち 「場の量」に対してのみ作用させることができる. なぜな ら,その定義式(1.16) の右辺は, 独立変数を αとtとするときの偏微分0/0tと ▽によって構成されているからである. aとtの任意関数 f(z,t) のラグラン ジュ微分は,式(1.15) を導いた過程から理解できるように, 流れに伴う f(x.t) の時間的変化の割合,すなわち, 流体粒子の軌跡に沿っての f(z,t) の時間的変 化の割合を表す。 十演算子▽をスカラー関数f(a)に作用させて得られるVfは, f の勾配 (gradient) とよばれ る。▽をスカラー関数に作用させたときは▽の代わりに grad という記号を使ってもよい。す なわち, ▽f=gradf. 後に述べるように, ▽をベクトルとみなしてベクトル関数に作用させ る(内積をとる)ときは, 記号 gradは使わない、ただし、式(1.13) の▽は grad を使って書 くことができる。

Vorld leaders are meeting to discuss this problem. Why is it such an important ISSU@? f the temperature of the earth rises too much, the polar ice CapS will begin to melt, causing the water level in the oceans to rise. The Intergovernmental Panel on Climate Change (the IPCC) has made Studies which suggest that there could be a one-meter rise in sea levels by the year 2080. No one knows exactly how bad the effect of this rise could be. However, it is thought that roughly 1 billion people who live on coastal land could experience severe impacts. The places most likely to be badly affected by this rise in sea level are tropical and warmer zoness: these are places where the coasts are more highly populated.
