Nadusha1986 [10]

Answer: $(0.081,\ 0.163)$

Step-by-step explanation:

Let $\hat{p}$ be the sample proportion.

As per given , we have

n= 411

$\hat{p}=\dfrac{50}{411}=0.121654501217\approx0.122$

Standard error : se=0.016

Critical value for 99% confidence : $z_{\alpha/2}=2.576$

Confidence interval for population proportion :-

$\hat{p}\pm z_{\alpha/2} (se)\\\\=0.122\pm (2.576)(0.016)\\\\=0.122\pm0.041216\\\\=(0.122-0.041216,\ 0.122+0.041216)\\\\=(0.080784,\ 0.163216)\approx(0.081,\ 0.163)$

Hence, the 99% confidence interval for the proportion of all US adults ages 55 to 64 to use online dating : $(0.081,\ 0.163)$
