For the following, determine what test to run. These answers include more than correlations and t-tests.
- A researcher wants to know if there is a relationship between whether or not a community has a neighborhood watch program (where residents walk the streets of the neighborhood) or not, and its rate of violent crimes over the past 12 months. What test would be used to assess this relationship?
2. Another researcher is also interested in the effectiveness of neighborhood watch programs but thinks they will have the most effect on burglaries. She examines the relationship between whether a community has a neighborhood watch program or not and whether or not burglaries are committed in the community. What test would you use?
- A researcher is interested whether participation in a formal after school activity or not is associated with a reduced risk for juvenile delinquency.

A researcher wants to determine whether high school students who attend an SAT preparation course score significantly different on the SAT than students who do not attend the preparation course. For those who do not attend the course, the population mean is 1050 (? = 1050). The 16 students who attend the preparation course average 1200on the SAT, with a sample standard deviation of 100. On the basis of these data, can the researcher conclude that the preparation course has...
