Question: Recent high profile legal cases have many people reevaluating the jury
Recent high-profile legal cases have many people reevaluating the jury system. Many believe that juries in criminal trials should be able to convict on less than a unanimous vote. To assess support for this idea, investigators asked each individual in a random sample of Californians whether they favored allowing conviction by a 10–2 verdict in criminal cases not involving the death penalty. The Associated Press (San Luis Obispo Telegram-Tribune, September 13, 1995) reported that 71% supported the 10–2 verdict. Suppose that the sample size for this survey was n = 900. Compute and interpret a 99% confidence interval for the proportion of Californians who favor the 10– 2 verdict.
