Students in an elementary school both boys and girls were asked if they are willing to write a letter to their mother on Mother's Day as an assignment. Out of the 30 boys, only 9 answered "yes" while out of the 45 girls, 39 said that they are willing to write to their mother on Mother's Day. At 99% level of confidence, is there enough evidence to say that the proportion who said "yes" is more for girls than boys? .
