Answer
The conclusions are different.
Work Step by Step
We want to see if the mean is different than $\frac{1404}{2000}=.702$, so we know $H_0: \mu = .702$ and $H_1: \mu \ne .702$. We now use a Ti-84 calculator. To solve, go to "Stat," then "Tests," and then select "Stats." Doing this, we find that the critical value and use a z-table calculator to find that p is less than .05, so the claim that $p_1\ne p_2$ is supported.
We use a ti-84 to find the confidence interval. To do this, we press “Stat” and then select “Tests.” Next, we select “2-PropZInt” to conduct the test. Doing this, we find that the confidence interval goes through 0, so we see that there is not a significant difference, meaning that $p_1=p_2$ is supported.
Thus, we see that the two results are different.
