I would like to test a hypothesis that the percentage of peoplewho consider themselves as conservatives today is lower than it was20 years ago. Conveniently enough, my old professor has data from20 years ago when he conducted a similar survey. The number ofpeople 20 years ago who identified as conservative in his surveywas 314 out of 612 total. I conduct a survey today and find thatout of the 415 people i surveyed, 198 considered themselves to beconservative. If i wish to present my findings with a level ofsignificance of .05, what conclusion would i draw?
options:
based on the data, there's evidence of a decrease in those whoidentify as conservative.
based on the data, there's no evidence of a decrease in thosewho identify as conservative.
based on the data, there's evidence of an increase in those whoidentify as conservative.
based on the data, there's no evidence of an increase in thosewho identify as conservative.
