According to a report, 74.1% of murders are committed with a firearm. (a) If 200 murders are randomly selected, how many would we expect to be committed with a firearm? (b) Would it be unusual to observe 167 murders by firearm in a random sample of 200 murders? Why? (a) We would expect nothing to be committed with a firearm. (b) Choose the correct answer below. A. No, because 167 is less than mu minus 2 sigma. B. Yes, because 167 is between mu minus 2 sigma and mu plus 2 sigma. C. Yes, because 167 is greater than mu plus 2 sigma .D. No, because 167 is between mu minus 2 sigma and mu plus 2 sigma . E. No, because 167 is greater than mu plus 2 sigma.
