**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:\[ \text{Lower Bound} < p < \text{Upper Bound} \]
