Answer: $(0.685,0.715)$

Step-by-step explanation:

The confidence interval for population proportion is given by :-

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

Given : Sample size : n= 2500

Number of people gave a positive answer = 1750

Then , Proportion of people gave a positive answer = $p=\dfrac{1750}{2500}=0.7$

Significance level : $\alpha= 1-0.9=0.1$

Critical value : $z_{\alpha/2}=1.645$

Now, the 90% two-sided confidence interval on the proportion of people who regularly have a dental checkup will be :-

$0.7\pm (1.645)\sqrt{\dfrac{0.7(0.3)}{2500}}\\\\\approx0.7\pm0.015\\\\=(0.7-0.015,0.7+0.015)\\\\=(0.685,0.715)$

Jane : 6

Lane : 3

Neesa : 213

So I think Jane is 6 inches tall or 1-1/5

My answer can be incorrect also so refer to Chrome too.
