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? .

A student randomly guesses at four multiple-choice questions. Each question has three possible choices. The random variable X denotes the number of correct answers. This experiment can be modeled as Oa) a normal experiment with mean 4 and standard deviation 1/3. O b) a normal experiment with mean 1/3 and standard deviation 4. O c) a binomial experiment with 3 trials and success probability 1/4. O d) a binomial experiment with mean 4 and standard deviation 1/3 O e) a binomial experiment with 4 trials and success probability 1/3.
