unusual behavior in people. The table shows the number
of arrests made in a small town during weeks of six full
moons and six other randomly selected weeks in the
same year. We wonder if there is evidence of a difference
in the types of illegal activity that take place.a) Will you test goodness-of-fit, homogeneity, or
independence?
b) Write appropriate null hypotheses.
c) Find the expected counts for each cell, and explain
why the chi-square procedures are not appropriate.

Property (burglary, vandalism, etc.) 17 21
Drugs/Alcohol 27 19
Domestic Abuse 11 14
