The study conducted help illustrate the Bakersfield resident’s perception of the Bakersfield Police. By administering, a survey on a sample group of one-hundred residents within Bakersfield city limits provided the necessary background need to develop ten hypotheses. The results for the ten hypotheses is discussed in detail below. Each hypothesis were run to demonstrate whether there was a statistical significance between the two variables. All hypothesis were translated using an adjusted standardized residual of + or – 1.96. By using an adjusted residual the groups illustrated where the majority of the relationship was concentrated. The first hypothesis which stated, there is a relationship between sex and the Bakersfield Police uses of excessive force was tested against the alpha level .05. According to the chi-square tests graph the cells had, a 25% expected count of less than five. This revealed that the test to follow was the likelihood ratio because the percentage was above 20. The likelihood ratio had a value count of 10.709, a degree of freedom of three and a p-value …show more content…

The alpha value used was .05. The test showed that there were 62.5% of the cells had an expected count less than 5. Since the percentage was larger than 20%, likelihood ratio showed a value of 22.937, a degree of freedom of 9 and a p-value of .006. The p-value of .006 and which is smaller than .05 required the null hypothesis was rejected. We were able to determine if there was a statistical significance between ethnicity and the belief that the Bakersfield Police treats all resident fairly regardless of race. This was achieved by using the contingency coefficient sine the graph was 4x4. The contingency coefficient had a value of .406 and a p-value of .020. The p-value revealed that there was a weak statistical
