[Satu ujian perbezaan berpasangan dengan ujian dua hujung menggunakan n = 10 pasang pemerhatian telah dijalankan. Diberi ) = 0.3 dan să = 0.16, apakah keputusan anda pada aras keertian 5% bagi menguji Ho: Md = 0,?] A. Reject Ho when t<tentical or t>-tcritical [Menolak Ho apabila t <tenitical atau t>-tertical] B. Reject Ho when t>tentical or t <-tenitical. [Menolak Ho apabila t > tcritical atau t-tertical.] C. Reject Ho when z> Zcritical or z<-Zcritical [Menolak Ho apabila z > Zcritical atau z < -Zertical) D. Reject Ho when z< Zcritical or z <-Zertical 4

Answer 1

Solution :- Hoi lid = 0 Ha: lid #0 This is the two tailed test 8 use t distribution So B Reject Ho, to teritical tc-tcritical or
