Question

求英语高手帮忙翻译下社会统计学的练习题><

Conduct T-test for differences in mean EARN between all pairs of SECTORS. Make a table to present the results. Then, in narrative, describe and interpret the results from the T-tests. Focus your interpretation on two questions: (1) Which pairs of sectors present significant differences in mean EARN? (2) When the significance level is less than 0.05, what does this mean?

ps:1.T-test:T检验
2.EARN、SECTORS都是变量，不译

From the Tianjin 1993 data, excluding SECTOR and EARN, choose ANY variable as a dependent variable and ANY variable as an independent variable that are suitable for performing a t-test for the difference in means between two groups. In this question, (1) raise a research question that requires comparing the means between two groups; (2) state your null hypothesis and alternative hypothesis in both verbal and notation forms; (3) obtain and present the appropriate statistical result; and (4) draw your conclusion about your hypothesized difference in means between the two chosen groups.

Answer 1

进行t意味着所有成对的部门之间收入的差异。做一个表显示结果。然后,在叙事,描述和解释t检验的结果。你解释关注两个问题:对部门存在显著差异意味着赚?显著性水平小于0.05时,这意味着什么呢?
从天津1993年数据,不包括部门和收入,选择任何变量作为因变量和变量作为一个独立变量,适用于执行t意味着两组之间的差异。在这个问题,提出一个研究问题,需要比较两组之间的手段;状态你的零假设和备择假设语言和符号形式;获取和现在适当的统计结果,和得出你的结论对你的假设之间的差异意味着两个选择组。
