Use the Given Degree of Confidence and Sample Data to Find

Use the given degree of confidence and sample data to find a confidence interval for the population standard deviation ?.
Assume that the population has a normal distribution. Round the confidence interval limits to one more decimal place than is used for the original set of data.
-The amounts (in ounces) of juice in eight randomly selected juice bottles are:
$15.0 \quad 15.915 .2 \quad 15.7$
$15.0 \quad 15.8 \quad 15.415 .4$
Find a $98 \%$ confidence interval for the population standard deviation $\sigma$ .

B) $0.22 \mathrm { oz } < \sigma < 0.72 \mathrm { oz }$
C) $0.22 \mathrm { oz } < \sigma < 0.83 \mathrm { oz }$
D) $0.21 \mathrm { oz } < \sigma < 0.72 \mathrm { oz }$
