老師好!題目如下: A client invest $40000 in four-year certificate of deposit(CD) that annually pays interest of 7%. The annual CD interest payments are automatically reinvested in a separate savings account at a stated annual interest rate of 4% compounded monthly. At maturity, the value of the combined asset is closest to: A 51 200.00 B 51 903.24 C 58 831.19 答案是B。 每年的interest payment 是2800,計(jì)算出EAR為I/Y,用計(jì)算器計(jì)算,為什么N是4不是48呢?謝謝!
中心極限定理中,x bar的個(gè)數(shù)要大于等于30,但是每個(gè)x bar的樣本量有個(gè)數(shù)要求嗎?比如總樣本30,000個(gè),分成30個(gè)組,每組1000個(gè)。然后從每組1000個(gè)抽樣。此時(shí)每組抽樣的個(gè)數(shù)有要求嗎?每組抽一個(gè),也有30組樣本,這樣也算滿足中心極限定理嗎?
老師,請(qǐng)問所有統(tǒng)計(jì)方法都不能表現(xiàn)經(jīng)濟(jì)學(xué)意義和因果關(guān)系?只能是統(tǒng)計(jì)學(xué),數(shù)學(xué)上的意義?那建模型干嘛,發(fā)現(xiàn)數(shù)據(jù)純技術(shù)分析嗎?

老師好!題目如下: A consultant starts a project today that will last for three years. Her compensation package includes the following: If she expects to invest these amounts at an annual interest rate of 3%, compounded annually until her retirement 10 years from now, the value at the end of 10 years is closest to. 題目中的annual interest rate和EAR的區(qū)別是什么呢?為什么計(jì)算中使用的是EAR而不是annual interest rate呢?感覺有點(diǎn)混亂。
為什么根號(hào)里要(1+10%)…而不是直接10%*9%…
