經濟學得考試題上次也練習了！但是每天都是學習練習的，這次CFA考試題學習也是CFA一級經濟學的科目，那這兩道考試題考察的是什么知識呢？
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.
