經(jīng)濟(jì)學(xué)得考試題上次也練習(xí)了！但是每天都是學(xué)習(xí)練習(xí)的，這次CFA考試題學(xué)習(xí)也是CFA一級(jí)經(jīng)濟(jì)學(xué)的科目，那這兩道考試題考察的是什么知識(shí)呢？

1. The confidence interval is most likely to be:

A. wider as the point estimate increases.

B. narrower as the reliability factor decreases.

C. wider as the sample size increases.

[Solution] A confidence interval for a parameter = Point estimate ± Reliability factor × Standard error. For example, the reliability factors for confidence intervals based on the standard normal distribution are 1.65 for 90% confidence intervals and 1.96 for 95% confidence intervals. For a given point estimate and standard error, the confidence interval will be narrower with a lower reliability factor.

2. The null hypothesis is most likely to be rejected when the p-value of the test statistic:

A. falls below a specified level of significance.

B. is negative.

C. exceeds a specified level of significance.

[Solution] If the p-value is less than the specified level of significance, the null hypothesis is rejected.

CFA知識(shí)學(xué)習(xí)是長期的事情，但是堅(jiān)持CFA考試是每一位學(xué)員應(yīng)該做到的。通過CFA考試掌握更多的金融知識(shí)，讓自己變成富有的人。更多CFA備考知識(shí)、資料領(lǐng)取及學(xué)習(xí)答疑的事情，學(xué)員可以在線咨詢老師或者添加老師微信。
