According to the Rule of Three, when we have a sample size n with x = 0 successes, we have 95% confidence that the true population proportion has an upper bound of n a. If n independent trials result in no successes, why can't we find confidence interval limits by using the methods described in this section? b. If 40 couples use a method of gender selection and each couple has a baby girl, what is the 95% upper bound for p, the proportion of all babies who are boys? a. Choose the correct answer below. O A. The requirement of at least 5 successes and at least 5 failures is not satisfied, so the normal distribution cannot be used. O B. The requirement of dependent trials is not satisfied, so the normal distribution cannot be used. O c. The requirement of at least 5 successes and at least 5 failures is not satisfied, so the binomial distribution cannot be used. O D. The requirement of dependent trials is not satisfied, so the binomial distribution cannot be used. b. The 95% upper bound for p, the proportion of all babies who are boys, is (Round to three decimal places as needed.)
