Example 11.2. Hypotheses with One Sample of One Categorical Variable
About 10% of the human population is left-handed. Suppose a researcher at Penn State speculates that students in the College of Arts and Architecture are more likely to be left-handed than people found in the general population. We only have one sample since we will be comparing a population proportion based on a sample value to a known population value.
Research Question: Are artists more likely to be left-handed than people found in the general population?
Response Variable: Classification of student as either right-handed or left handed
State Null and Alternative Hypotheses
Null Hypothesis: Students in the College of Arts and Architecture are no more likely to be left-handed than people in the general population (population percent of left-handed students in the College of Art and Architecture = 10% or p = .10).
Alternative Hypothesis: Students in the College of Arts and Architecture are more likely to be left-handed than people in the general population (population percent of left-handed students in the College of Art and Architecture > 10% or p > .10). This is a one-sided alternative hypothesis.
