Question
A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.20. In a sample of 200 graduates, 30 students have a GPA of 3.00 or below. The value of the test statistic and its associated p-value are ________

Transcribed Image Text:**Hypothesis Testing Example for University Honors Program**
A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.20. In a sample of 200 graduates, 30 students have a GPA of 3.00 or below. The value of the test statistic and its associated *p*-value are __________.
**Multiple Choice:**
1. \( t_{199} = -1.77 \) and *p*-value = 0.0385
2. \( t_{199} = -1.77 \) and *p*-value = 0.0768
3. \( z = -1.77 \) and *p*-value = 0.0768
4. \( z = -1.77 \) and *p*-value = 0.0385
**Explanation:**
This is a hypothesis testing problem where we are given a sample of 200 graduates, out of which 30 have a GPA of 3.00 or below. We need to determine the test statistic and *p*-value for the hypothesis that the proportion (\( p \)) of students with a GPA of 3.00 or below is less than 0.20.
Students should select the correct test statistic and *p*-value from the options provided. The test statistic could either be a *t*-value or a *z*-value, depending on the sample size and assumptions.
