Male	13	12	6	31
Female	2	10	5	17
Total	15	22	11	48

Let $\displaystyle \pi$ represent the percentage of all male students who would receive a grade of A on this test. Use a 98% confidence interval to estimate $\displaystyle \pi$ to three decimal places.

Enter your answer as a tri-linear inequality using decimals (not percents).
