Answer:


0.61 \leq p \leq 0.70

And for this case we can estimate the proportion of households who recycle paper is given by:


\hat p = (Upper +Lower)/(2)

And replacing we got:


\hat p =(0.7+0.61)/(2)= 0.655

And for this case the answer is 0.655 for the proportion of households who recycle paper

Explanation:

For this case we know that the confidence interval for the proportion of interest is given by:


\hat p \pm z_(\alpha/2) \sqrt{(\hat p (1-\hat p))/(n)}

And for this case the confidence interval is given:


0.61 \leq p \leq 0.70

And for this case we can estimate the proportion of households who recycle paper is given by:


\hat p = (Upper +Lower)/(2)

And replacing we got:


\hat p =(0.7+0.61)/(2)= 0.655

And for this case the answer is 0.655 for the proportion of households who recycle paper
