When a police officer responds to a call for help in a case of spousal abuse, what should the officer do? A randomized controlled experiment in Charlotte, North Carolina studied three police responses to spousal abuse advise and possibly separate the couple, Issue a citation to the offender, and arrest the offender, The effectiveness of the three responses was determined by re-arrest rates. The table below shows these rates Assigned Treatment Arrest Citation Advise/Separate of Re arrests 0 1 2. 3 4 175 36 2 1 0 181 33 7 1 2 187 24 1 0 0 Suppose we wish to test the null hypothesis that the proportion of subsequent arrests is the same regardless of the treatment assigned. Which of the following statements is true? The test of the null hypothesis will have a very small P-value (below 0001) because the there were so tew cases where there were more than one re-arrest. We cannot test this hypothesis because the police others did not record the expected counts. The test of the null hypothesis will have a very small P value (bielow.0001) because the counts in each row are not identical We cannot test this hypothesis because the expected cell counts are less than five in too many of the cells
