A local police chief reported that 46% of all drug-related arrests are never prosecuted. A simple random sample of 845 arrests shows that 44.5% of the arrests were not prosecuted. Using this information, one officer wants to test the claim that the number of arrests that are never prosecuted is less than what the chief reported. Is there enough evidence at the 10% significance level to support the officer's claim?
Step 2 of 5 : Calculate the test statistic. Round your answer to two decimal places.
