Table 3 below gives the test for pre-deliberation ballot. We clearly see that there is an association between death-qualified jurors and those who would have been excluded in regard to the voting. The p-value is given as 0.017 (a value less than α=0.05), leading to the rejection of the null hypothesis and thus we conclude that there is significant difference in the voting pattern between death-qualified jurors and those who would have been excluded Table 4 below gives the test for post-deliberation ballot.

We again see that there is an association between death-qualified jurors and those who would have been excluded in regard to the voting. The p-value is given as 0.017 (a value less than α=0.05), leading to the rejection of the null hypothesis and thus we conclude that there is significant difference in the voting pattern between death-qualified jurors and those who would have been excluded The p-value for the Pearson’s Chi-square is 0.256 (a value greater than α=0.05), we thus fail to reject the null hypothesis and conclude that there is no association between ethnicity and the examination pass rate.

The p-value for the Fisher Exact test to test is 0.375 (a value greater than α=0.05), we thus fail to reject the null hypothesis and conclude that there is no association between ethnicity and the examination pass rate. d. Use the 2-sample Z-test method to test the null hypothesis that the pass rates are equal for Hispanic and other officers. Explain the results, and compare the results from the three tests you performed in B,C,D. From the table we observe the mean for other officers to be 1.

78 while that of Hispanic officers is 1.88. The p-value for the 2-sample Z-test is 0.693419 (a value greater than α=0.05), we thus fail to reject the null hypothesis and conclude that there is no significant difference in pass rate between the Hispanic officers and other
