请问查表得出CV以后 怎么算出置信区间？

The coupon interest of a dual-currency bond is paid in a currency: A of the bondholder's choice. B other than the home currency of the issuer. C other than the currency in which it repays principal. 老师您好，能否单纯从翻译的角度解析下B C选项的区别，性质我知道，但是在具体阅读理解中犯困或了

B选项，AS降低，AS线不应该是左移动嘛？如果考虑是long-run，那AS曲线也是垂直的左移么？？

brief后必须附详细说明吗，都包括哪些

Bill Fence, CFA, supervises a group of research analysts, none of whom have earned the CFA designation or are CFA candidates. On several occasions he has attempted to get his firm to adopt a compliance system to ensure that applicable laws and regulations are followed. However, the firm's principals have never adopted his recommendations. Fence should most appropriately: A resign from the firm, because no other alternative will keep him in compliance with the Code and Standards. B decline in writing to accept supervisory responsibility until reasonable compliance procedures are adopted. C take no further action, because by encouraging his firm to adopt a compliance system he has fulfilled his obligations under the Code and Standards. B选项中的decline in 怎么理解？是减少的意思吗？ B选项整个句子的含义让我蒙了

Which of the following statements is correct under the Code and Standards? A CFA Institute members and candidates are prohibited from undertaking independent practice in competition with their employer. B Written consent from the employer is necessary to permit independent practice that could result in compensation or other benefits in competition with a member’s or candidate’s employer. C Members and candidates are prohibited from making arrangements or preparations to go into a competitive business before terminating their relationship with their employer 老师您好，解析下C为啥不对

Nick O'Donnell, CFA, unsuspectingly joins the research team at Wickett & Co., an investment banking firm controlled by organized crime. None of the managers at Wickett are CFA Institute members. Because of his tenuous situation at Wickett, O'Donnell begins making preparations for independent practice. He knows he will be terminated if he informs management at Wickett that he is preparing to leave. Consequently, he determines that "if he can just hang on for one year, he will likely have a client base sufficient for him to strike out on his own." This action is: A a violation of his fiduciary duties. B not a violation of his duty to employer. C a violation of his duty to disclose conflicts to his employer. 这道题需要老师帮我解析， C为什么不对？
