Question

A study in the Los Angeles Times reported that the number of liquor stores in a neighborhood has a strong positive linear association with the amount of crime in that neighborhood. What can you determine about the relationship between the number of liquor stores and the amount of crime?

Select one:

a. Neighborhoods with a higher number of liquor stores tend to have a higher amount of crimes.

b. No conclusions can be drawn without seeing a scatterplot of the data.

c. People who live in neighborhoods with more liquor stores commit more crimes.

d. If we decrease the number of liquor stores in a neighborhood, the amount of crimes will decrease.

Explanation / Answer

Solution:

Option a is correct.

Since there is strong and positive linear association between number of liquor stores in a neighborhood and amount of crime in that neighborhood. As one variable increases, another variable also increases. Neighborhoods with higher-than-average number of liquor stores typically (but not always) have a higher-than-average crime rate.
