Question

A ______ alternative hypothesis such as ______ is also referred to as ______.
A) directional; µ ≠ 164; two-tailed
B) non-directional; µ > 164; two-tailed
C) directional; µ > 164; one-tailed
D) non-directional; µ ≠ 164; one-tailed

Quizplus · Accepted Answer

A directional alternative hypothesis specifies the direction of the effect, while a non-directional alternative hypothesis does not. In this case, the alternative hypothesis states that the population mean is greater than 164, so it is directional. A one-tailed test is appropriate because we are only interested in one direction of the effect (greater than 164).
