In the following problem, check that it is appropriate to usethe normal approximation to the binomial. Then use the normaldistribution to estimate the requested probabilities.What are the chances that a person who is murdered actually knewthe murderer? The answer to this question explains why a lot ofpolice detective work begins with relatives and friends of thevictim! About 61% of people who are murdered actuallyknew the person who committed the murder.† Suppose that adetective file in New Orleans has 60 current unsolvedmurders. Find the following probabilities.
