已回答这道题两个问题,一是为什么计算出假设检验量2.6后,老师说这个分布既服从80的t分布,又符合0,1的正态分布,这两个分布很接近吗?为什么这里用了正态分布却不用t分布呢?二是2.33右边的面积为什么是1%?为什么不是0.5%?前面几道题对应95%的置信区间都用的单边2.5%,那这里99%不是应该单边算0.5%吗?

已回答老师,图片中的公式不是说利率上升,期货价格上升吗 但是下面这个题目的答案是利率上升使得期货价格下降 A German housing corporation needs to hedge against rising interest rates. It has chosen to use futures on 10-year German government bonds. Which position in the futures should the corporation take, and why? A、Take a long position in the futures because rising interest rates lead to rising futures prices. B、Take a short position in the futures because rising interest rates lead to rising futures prices. C、Take a short position in the futures because rising interest rates lead to declining futures prices. D、Take a long position in the futures because rising interest rates lead to declining futures prices. 答案:C 解析: Government bond futures decline in value when interest rates rise, so the housing corporation should short futures to hedge against rising interest rates.

- 我怎么感觉这题不太对呢。特别是C/D两个,都是需要股价上去才可能有利,所以逻辑是一样啊,都是做高业绩,但是C反正都遥遥无期,动力没那么足吧。B现在是平值,就差那一把火就能盈利了所以应该最要努力把业绩做起来吧?A也是,你既然都深度实值了,赶紧卖了得了,还做什么风险管理。这题我都不懂
