According to a report, 67.3% of murders are committed with a firearm. (a) If 100 murders are randomly selected, how many would we expect to be committed with a firearm? (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. OA. No, because 78 is less than μ-20. 20. OB. No, because 78 is greater than μ + OC. Yes, because 78 is greater than μ + 2o. O D. No, because 78 is between μ-20 and μ + 2o. OE. Yes, because 78 is between μ-20 and μ+ 20.
