(b) Would it be unusual to observe 78 murders by firearm in a random sample of 100 murders? Why? ..... (a) We would expect to be committed with a firearm. (b) Choose the correct answer below. O A. No, because 78 is greater than u + 20. O B. Yes, because 78 is between u - 2o and µ + 20. O C. Yes, because 78 is greater than u + 2o. D. No, because 78 is between u- 20 and u + 20. E. No, because 78 is less than u- 20.
