The test statistic of 0.54 does not fall within the critical region, which suggests that the difference between the level of support for the new immigration policy among Republicans and Democrats is not statistically significant. Therefore, we can conclude that there is no difference between the parties on this issue at a significant level, and we cannot reject the null hypothesis.
