计量经济学的一个基本工具是多元线性回归 multiple linear regression模型。计量经济学理论使用统计理论statistical theory和数理统计mathematical statistics来评估和发展计量经济学方法。计量经济学家试图找到具有理想统计特性的估计量estimators,包括无偏性 unbiasedness、效率Efficiency (statistics)和一致性Consistency (statistics)。应用计量经济学使用理论计量经济学和现实世界的数据来评估经济理论,开发计量经济学模型Econometric model,分析经济历史Economic history和预测Economic forecasting。
a) The null: The proportion of registered voters who are planning to vote for the incument president <0.5
The alternative: The proportion of registered voters who are planning to vote for the incument president ≥0.5
b) Test statistic=(636/1200-0.5)/sqrt(0.5*0.5/1200)=2.08
c) CV is Z0.05=1.64
d) From the standard normal table, the p-value for the test statistic, z = 2.08 is 1-0.9812=0.0188.
e) Since p-value is lower than 0.05, we reject the null and conclude that the proportion of registered voters who are planning to vote for the incument president increases significantly at 5% significance level.
f) We say the proportion of registered voters who are planning to vote for the incument president increases significantly, while in fact it does not.
g) We say the proportion of registered voters who are planning to vote for the incument president does not increases significantly, while in fact it does.
