Question

The results of a survey indicate that the true proportion of households who recycle paper products
is likely in the interval (0.61,0.7).
What is the point estimate of the proportion of households who recycle paper?
Enter your answer, as a decimal, in the box.​

Answer 1

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:

$\hat p = \frac{Upper +Lower}{2}$

And replacing we got:

$\hat p =\frac{0.7+0.61}{2}= 0.655$

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

Step-by-step explanation:

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

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

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:

$\hat p = \frac{Upper +Lower}{2}$

And replacing we got:

$\hat p =\frac{0.7+0.61}{2}= 0.655$

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