Question

According to the Rule of Three, when we have a sample size n with x =0 su a. If n independent trials result in no successes, why can't we find confidence b. If 40 couples use a method of gender selection and each couple has a bab a. Choose the correct answer below O A. The requirement of at least 5 successes and at least 5 failures is not sa O B. The requirement of at least 5 successes and at least 5 failures is not sa O C. The requirement of dependent trials is not satisfied, so the normal distrib O D. The requirement of dependent trials is not satisfied, so the binomial distri Click to select your answer and then click Check Answer part remaining

Explanation / Answer

Answer to the question)

The rule of three applies pretty well for large samples, but when we deal with small samples the rule fails to satisfy the condition that there must be atleast 5 successes and 5 failures

It is important to have atleast 5 successes and 5 failures in order to find the confidence intervals for proportions or binomial probability

Thus we cannot find confidence interval for binomial probabilities in case if there is no success, because the basic requirement of atleast 5 successes is not satisfied by it.
