In general, it is not. A one-tailed test is more powerful but it does require the alternative hypothesis to be one sided and, in therefore requires some expectation about the observations if the null hypothesis is not true.
The question, therefore, is appropriate only when the experimenter has extremely limited information about the experiment - not a very common occurrence.

Differences between triaxial test and shear box test?
Shear box tests are generally suitable for cohensionless soil except fine sand and silt whereas triaxial test is suitable for all types of soils. Pressure changes and volume changes can be measured directly in triaxial test which is not possible in shear box test. Pore water pressure can be measured in the case of triaxial test which is not possible in direct shear test. Triaxial machine is more adaptable. The stress distribution across the soil sample in the failure plane is more uniform in triaxial test. The complete state of stress is known at all intermediate stages up to failure during the triaxial test whereas only the stress at failure are known in the direct shear test. In triaxial test, there is complete control over the drainage conditions, where control of drainage conditions is very difficult in shear box test.
Difference between test condition and test scenario?
1) Test Condition is a process to test an application where as Test Sc enario is the way to test test an application. 2) Take an Example of Login Screen where Test Condition is; after entering UserName and Password, home page will come. But in case of Test Scenario,you can do this by so many ways like +ve testing, -ve testing etc.
What is a t-test?
a t test is used inplace of a z-test when the population standard deviation is unknown.
Why shouldn't you cram for a skills test?
Cramming for a skills test can lower your performance and increase your test anxiety.
What are difference between uniformly most powerful test and most power test?
the mp test is only for a specified value of hypothesis and the UMP test is for a set of values
