Answer:

$99\% CI=4.1602 \pm 0.0009$

Step-by-step explanation:

From the question we are told that:

Sample size $n=8$

Mean $\=x=4.1602$

Standard deviation $\sigma=0.001gram$

Generally 99\% confidence from table is mathematically given by

$99\% CI=4.1602 \pm *2.576*\frac{0.001}{\sqrt{{8}}}$

$P(-z$

$Z_{\alpha/2}=2.576$

Generally the equation for 99\% confidence level (CI) is mathematically given by

$99\% CI=\=x \pm Z_{\alpha/2*\frac{\sigma}{\sqrt{{n}}}$

$99\% CI=4.1602 \pm 0.0009$
