I would like to test a hypothesis that the percentage of people who consider themselves as conservatives today is lower than it was 20 years ago. Conveniently enough, my old professor has data from 20 years ago when he conducted a similar survey. The number of people 20 years ago who identified as conservative in his survey was 314 out of 612 total. I conduct a survey today and find that out of the 415 people i surveyed, 198 considered themselves to be conservative. If i wish to present my findings with a level of significance of .05, what conclusion would i draw?

options:

based on the data, there's evidence of a decrease in those who identify as conservative.

based on the data, there's no evidence of a decrease in those who identify as conservative.

based on the data, there's evidence of an increase in those who identify as conservative.

based on the data, there's no evidence of an increase in those who identify as conservative.
