Answer #1

To compare Democrats and Republicans in their responses, the suitable statistical tools is independent t- test and the hypothesis could be one tail test that will stated as follow:
Ho: u1=u2(there is no significant difference between Democrats and Republicans)
H1: u1>u2( Democrats is more significantly greater than Republicans)

Or hypothesis for two tail test as follows
Ho: there is no significant difference between Democrats and Republicans
H1: there is a significant difference between them.

The major assumption that supported the choice of independent t statistics is that the variables must be independent of each other and this is satisfied here.
