Suppose that a random sample of 60 horror movies containing 100 character deaths was collected. Among the characters who died, 44% were female. a) Suppose that you'd like to estimate the true proportion of deaths in horror movies that are female deaths within a margin of error of 3% with 95% confidence. How many character deaths would you have to witness in order to achieve this margin of error? b) Calculate a 95% confidence interval for the true proportion of deaths that are female deaths in horror movies, using our original sample.

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.
