You are interested in examining the effect of the number of prior arrest(s) on recidivism. The table below shows the number of prior arrests for a random sample of 8 offenders and the number of subsequent offense(s), i.e., recidivism, committed by each offender in the previous year. Use the information below to answer the following questions.

# of Prior Arrest(s) # of Subsequent Offense(s)

2 0

3 3

1 4

1 5

4 4

6 4

2 1

2 5

1) State your independent and dependent variables 2) Compute the value of the slope "b" 3) Interpret the slope coefficient (i.e., what is the direction of the relationship between age and delinquency? 4) Compute the value of the intercept "a" 5) Construct the regression equation 6) Use the above regression equation to predict the number of subsequent offense(s) for an offender who has 2 prior arrests

According to extant evidence, the effect of arresting domestic offenders on their recidivism is inconsistent. You conducted your own research using a sample of 270 domestic offenders and found the following results:

Recidivism Increased	Recidivism Decreased	Did Not Recidivate
105	95	70

Use the above data to answer the following questions: 1) State the null and research hypotheses 2) Indicate the appropriate statistical test 3) With the significance level set at .01, specify your critical value 4) Report the obtained value 5) Declare your decision (i.e., whether to reject or retain the H0; 6) What can you conclude in terms of the observed frequencies in recidivism among the three categories of domestic violence offenders ?

Suppose you are interested in determining the link between stalking and severe intimate partner violence. You hypothesize that domestic violence victims whose partners also stalk them suffer more severe and serious injuries relative to domestic violence victims whose partners do not stalk them. You surveyed a group of 32 domestic violence victims and found the correlation between stalking and severe intimate partner violence was 0.82. Conduct a statistical test to determine if the correlation between the above two variables obtained from your sample is different from the true correlation in the population.

1) State the null and research hypotheses 2) Indicate the appropriate statistical test 3) With the significance level set at .05, specify your critical value 4) Describe thedirectionandmagnitudeof the obtained correlation 5) Declare your decision (i.e., whether to reject or retain the H0; . 6) Explain your decision .
