Question

Show all work to receive full credit Does familiarity with neighbors lead to lower crime rates? A researcher has theorized that if neighbors know each other, then the crime rates will be lower than in communities in which neighbors do not have a relationship. When communities grow quickly the closeness of the community degrades. A study was done to see if there is a relationship between the crime rate and the percentage change in neighborhood population. 10 neighborhoods in a large metropolis were studied. The results are as follows. Percentage Change in Neighborhood Population 29 2 11 17 7 6 51 13 19 7 Crime Rate (Crime per 1000 population) 173 35 132 127 69 53 223 104 99 45. Make a scatter pot of the data. Does the scatter plot show a significant linear relationship?

Explanation / Answer

It seems from the scatter plot that it is a significant linear relationship.
