Researchers reported a study in which 409 domestic violence defendants were randomly assigned to counseling and probation (the experimental group) or just probation (the control group). Out of people 238 in the counseling group, 51 were arrested within 12 months. Out of 171 people assigned to probation,41 were arrested within 12 months. Determine whether counseling lowered the arrestrate; use a 0.05 significance level. Start by comparing the percentages.1. Write the hypothesis for the test. Ho ___ Ha ____2. z = ___ (Round to two decimal places asneeded.)3. p-value = ____ (Round to three decimal places asneeded.)4. What is the conclusion for this test? Use a significance level of 0.05.
