Crime concerns in China.

A 2013 poll found that 22.2% of Chinese adults see crime as a very big problem, and the standard error for this estimate, which can reasonably be modeled using a normal distribution, is SE = 1.4%. Suppose an issue will get special attention from the Chinese government if more than 1-in-5 Chinese adults (20%) express concern on an issue.

  1. Calculate a z-score using the observed percentage and the two model parameters. Round to four decimal places.
  2. Use the normal model to calculate a p-value. Round to four decimal places
