![**Student Grades Summary**
In a test given to a group of students, grades based on gender are summarized in the table below:
| | A | B | C | Total |
|-------|----|----|----|-------|
| Male | 18 | 15 | 11 | 44 |
| Female| 3 | 7 | 16 | 26 |
| Total | 21 | 22 | 27 | 70 |
**Objective:**
Let \( p \) represent the population proportion of all male students who received a grade of C on this test. Your task is to use a 99.5% confidence interval to estimate \( p \) to four decimal places if possible.
Insert the calculated interval in the space provided:
\[ \text{Lower Bound} < p < \text{Upper Bound} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7248d714-2630-4255-aa39-67ac8596a103%2F2c4d271c-0684-4a96-9811-da1fdf5aaf5b%2Ftb2gbtf_processed.png&w=3840&q=75)
