We hypothesize that, the more that residents of a country feel that religion is very or rather important, the more the people of that country will strongly agree or agree that their own religion is the only acceptable religion. But we suspect that this might be a nonlinear relationship. Run two regression models using WVS data, with RELACCEPT as the dependent variable. In the first, use only the RELIGIONIMP variable as your independent variable. Then, in the second model, add the square of the RELIGIONIMP variable: RELIGIONIMPSQRD. Write up your results, including a graph, and explain them.
