Answer:

$1124.28 \text { to } 1220.94$

Step-by-step explanation:

A 99% confidence interval for the mean sodium content in Oriental Spice Sauce is,

First, compute t -critical value then find confidence interval.

The t critical value is,

The sample size is small and two-tailed test. Look in the column headed $\alpha=0.01$ and the row headed in the t distribution table by using degree of freedom is,

d . f . =n-1

=170-1

=169

The t critical value is 2.605 .

$99 \% \text { C.I. } &=\bar{x} \pm t_{c} \times s / \sqrt{n}$

$=1172.61 \pm 2.605 \times 241.88 / \sqrt{170}$

$=1172.61 \pm 48.33$

$=1124.28 \text { to } 1220.94$

A $99%$ confidence interval for the mean sodium content in Oriental Spice Sauce is

$1124.28 \text { to } 1220.94$
