Use the One-Standard-Deviation Chi-Square Interval Procedure to Obtain the Specified $\sigma$

Multiple Choice

Use the one-standard-deviation chi-square interval procedure to obtain the specified confidence interval for the population standard deviation $\sigma$ . Assume that the population has a normal distribution.
-The amounts (in ounces) of juice in eight randomly selected juice bottles are:
$\begin{array}{llll}15.3 & 15.3 & 15.8 & 15.2 \\ 15.4 & 15.3 & 15.9 & 15.2\end{array}$

B) $0.16$ to $0.56 \mathrm { oz }$
C) $0.17$ to $0.64 \mathrm { oz }$
