A researcher administers a treatment to a sample of n 50 pa

A researcher administers a treatment to a sample of n = 50 participants and uses a hypothesis test to evaluate the effect of the treatment. The hypothesis test produces a z-score of z = 1.37. Assuming that the researcher is using a one-tailed test with alpha = .05, what decision should be made?

Solution

Critical Value
The Value of |Z ?| at LOS 0.05% is 1.64
We got |Zo| =1.37 & | Z ? | =1.64
Make Decision
Hence Value of | Zo | < | Z ?| and Here we Do not Reject Ho or Failed to Reject Ho
