Answer:

$0.12 -1.96*0.013= 0.094$

$0.12 +1.96*0.013= 0.146$

And the best option would be:

0.094 to 0.146

Step-by-step explanation:

For this case we have the following info given:

$\hat p=0.12$ represent the proportion estimated

$SE = 0.013$ represent the standard error

$Confidence =0.95$ represent the confidence level

The confidence interval for the true proportion is given by:

$\hat p \pm z_{\alpha/2} SE$

And for 95% of confidence the critical value is $z_{\alpha/2}= 1.96$ and replacing we got:

$0.12 -1.96*0.013= 0.094$

$0.12 +1.96*0.013= 0.146$

And the best option would be:

0.094 to 0.146
