Crime concerns in China. A 2013 poll found that 24.2% of Chineseadults see crime as a very big problem, and the standard error forthis estimate, which can reasonably be modeled using a normaldistribution, is SE = 1.3%. Suppose an issue will get specialattention from the Chinese government if more than 1-in-5 Chineseadults express concern on an issue.

1. Choose words from the dropdown choices to constructhypotheses regarding whether or not crime should receive specialattention by the Chinese government according to the 1-in-5guideline. Before making your choices consider the appropriatenessof using a one-sided or two-sided test for this exercise. That is,for this decision process, would we care about one or bothdirections?

2. Calculate a z-score using the observed percentage and the twomodel parameters. Round to four decimal places. z =

3. Use the normal model to calculate a p-value. Round to fourdecimal places. p =

4. Based on your p-value, should crime receive special attentionfrom the Chinese government?
