John believes that height is related to leadership and specifically hypothesizes that the taller one is, the more other people look to that person as a leader. To test this hypothesis, he randomly selects a sample of 50 people, and measures their height and perceived leadership potential (both quantitative measures). This is a hypothesis and will result in a(n) -tailed test

This is a __simple hypothesis and will result in a(n) one-tailed test.

Step-by-step explanation:

The Simple Hypothesis predicts the relationship between two variables, in this case, height and leadership. The one-tailed test will be performed to determine whether to reject the null hypothesis.  This is why the null and alternative hypotheses must be established before the statistic test is carried out.   If the null hypothesis is rejected, this simply results in the acceptance of the alternative hypothesis.
