Question

The mayor of a large city started a "crime-line" program some years ago and wonders whether it is working. the program publicizes unsolved violent crimes in the local media and offers cash rewards for information leading to arrests. a sample of 178 crimes featured on the crime-line found that 35% are cleared by arrest, and a sample of 212 crimes not on the crime-line found that 25% are cleared by arrest. are "featured" crimes more likely to be cleared by arrest than other violent crimes?

Answer 1

The clearance rate for 'featured' crimes is higher than the clearance rate for other violent crimes, indicating that 'featured' crimes are more likely to be cleared by arrest.

Step-by-step explanation:

To determine whether 'featured' crimes are more likely to be cleared by arrest than other violent crimes, we compare the clearance rates of crimes on the crime-line and crimes not on the crime-line.

The sample of 178 'featured' crimes found that 35% were cleared by arrest, while the sample of 212 crimes not on the crime-line found that 25% were cleared by arrest.

We can see that the clearance rate for 'featured' crimes is higher than the clearance rate for other violent crimes. Therefore, we can conclude that 'featured' crimes are more likely to be cleared by arrest than other violent crimes.
