A z-test? That would make sense only if we knew thestandard errors with certainty. If we have to estimate thestandard error, it becomes a t-test. Also, you've given me 4Z-scores, and I count only 2 test statistics to calculate in theproblem. . Is there any more information about the problem? Whatmethods were covered in the chapter? Are those z-scoressupposed to be answers to this problem, or to a related problem,and if so, what was one of those problems? Give me somemore context here!Related Questions
