Answer 1

Null and alternative Hypothesis, Ho: Age Category and Opinion are independent. H1: Age Category and Opinion are dependent.

Chi-Square Tests Value df Asymp. Sig (2-sided Pearson Chi-Square Likelihood Ratio Linear-by-Linear Association N ofValid Cases a. O cells (0.0%) have expected countless than 5 . The minimum expected count is 26.68 20.799a 20.951 1.983 401 0.002 0.002 0.159 Chi-square test statistic is Chi-square-Σ(Oi-Ei)2-20799 P-value-0.002 Conclusion: The P-value of Pearson Chi-square test is less than 0.05. Thus, we reject null hypothesis at 5% level of significance and conclude that Age Category and Opinion are dependent. Hence on the basis of above conclusion, we say that the Americans in favor of the use of unmanned drones by police agencies in the United States because Age Category and Opinion are dependent.
