ConductT-testfordifferencesinmeanEARNbetweenallpairsofSECTORS.Makeatabletopresentther...
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.
