OverLord2011 [107]

Answer: $(0.9460\ ,\ 0.9500)$

Step-by-step explanation:

Given : Population mean : $\mu=0.9480$

Standard deviation : $\sigma=0.0060$

Sample size : n=35

Significance level : $\alpha=1-0.95=0.05$

Critical value = $z_{\alpha/2}=\pm1.96$

The confidence interval for sample mean is given by :-

$\mu\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

i.e. $0.9480\pm (1.96)\dfrac{0.0060}{\sqrt{35}}$

$\approx0.9480\pm0.0020=(0.9480-0.0020\ ,\ 0.9480+0.0020)\\\\=(0.9460\ ,\ 0.9500)$

Hence, the required interval= $(0.9460\ ,\ 0.9500)$
