Final Answer : C, Explanation :  A directional alternative hypothesis has a greater than symbol if the researcher is predicting a specific direction of effect (e.g. the treatment group will have higher scores than the control group). This is also referred to as a one-tailed hypothesis. The other options are incorrect - a non-directional alternative hypothesis has an equal symbol (option B), and a one-tailed hypothesis cannot have a not-equal symbol (options A and D).

A) directional; ≠ ; two-tailed
B) non-directional; =; two-tailed
C) directional; >; one-tailed
D) non-directional; ≠; one-tailed
