Question

In hypothesis testing, it is easier to reject H₀ with a ______________

directional test (one tail)

with a non-directional test ( two tailed)

when treatment has no effect

Answer 1

Answer #1

The correct answer is " directional test (one tail) "

● In hypothesis testing, it is easier to reject Ho with a directional test (one tail)

non-directional hypothesis is a type of alternative hypothesis.
