A campus survey asked two independent random samples of students whether they participate in a student recycling program and whether they participate in a campus composting program. The recycling sample had $n_R=400$ with $x_R=260$ saying yes. The composting sample had $n_C=350$ with $x_C=210$ saying yes. At the $\alpha =0.05$ level, is there evidence the proportions differ? Use a two-sided test.

• A. There is enough evidence to reject the null hypothesis and conclude that the proportions differ
• B. There is not enough evidence to reject the null hypothesis, and the proportions are not significantly different
• C. There is enough evidence to reject the null hypothesis and conclude that the proportions are equal
• D. There is not enough evidence to reject the null hypothesis, and the proportions are significantly different

Answer: (B)
