Use prop.test() command to construct a 95% confidence interval for comparing p1 and p2. Can you conclude which of p1 and p2 is larger? Explain. (c) Test your conclusion in (b) at the .05 level using prop.test() command. You only need to show your code and output. (d) Interpret the reported p-value.
